How Hard is a PhD?

Amongst the general population, having a PhD is often seen as the pinnacle of academic achievements but how hard is it to achieve?

Having passed my PhD viva yesterday I now feel I’m in a position to really judge how difficult a PhD is!

A dive into the unknown

Any time we don’t have experience in something, the element of the unknown can make it hard to evaluate how hard it is.

Coming from your previous qualifications you may extrapolate and think that since your undergraduate degree was a step up from high school in work and difficulty, a PhD must be another step change in difficulty.

With PhDs it’s not helped by the fact that a lot of the time only the most academically capable students are interested in them, which may make you think you have to be really clever to do one. Plus, as they’re not that common it’s not always easy to find people with experience to speak to.

Growing up I didn’t know anyone who had done a PhD degree, heck none of my immediate family had been to university, so I appreciate that gaining an insight about PhDs isn’t available to everyone.

So how hard is a PhD?

The reality is that a PhD can be difficult, but mostly it’s just different.

How hard you might find certain aspects of a PhD really depend on your own working style and to a lesser extent personality. Let’s discuss the factors one by one.

How hard is it to manage the PhD workload?

During a PhD there will be times you have to stay late, or work weekends (every so often) but it’s nothing like undergraduate degrees, with relentless deadlines and all-nighters being a regular occurrence for a lot of us.

Something that studying for a PhD does have in common with undergrad is that there is always more work that you can get on with, which can be disconcerting. Though unlike undergrad this feeling doesn’t stop after exams where you can enjoy a long study-free summer, because there are no term times for a PhD. I’ve previously shared how much holiday I’ve taken as a PhD student.

You need to find a way to switch off, otherwise your mental health will suffer.

Prior to starting my PhD I worked as a research assistant for three years and I found it helpful to view my PhD as a full time job. Even all the way through to submitting my thesis, working consistently 9-5ish every day was enough. I do hear of people working every hour of the week but these are the exception rather than the norm.

For a deeper insight into my typical working schedule check out the post below where I shared my calendar.

How Much Work is a PhD?

PhD depth and breadth of study

If you’ve been in higher education for a while, you’ll have probably got used to learning a wide amount of topics in a short time. Topics are covered at a fast pace, sometimes in not much detail, without much time to build your understanding.

I can’t have been the only person who during undergrad was effectively have to fight fires, not having much time to concentrate and fully understand each topic before having to move on to the next one.

PhDs provide a step-change, where you focus in on a single topic to a much greater depth.

For most PhDs there will be a certain amount of knowledge you’re expected to have picked up from your previous degree(s), but the pace of a PhD is undoubtedly much more slow. The reality is that the breadth of a PhD topic is really quite limited, though it can often span several disciplines. It’s common for your project to involve topics you’re not completely comfortable with.

You have a lot of time to focus on just one topic and you’re expected and required to know the topic inside out. The good news is that you’re given more than adequate time to learn the ropes.

As a PhD student there is nothing wrong with refreshing your knowledge of basic topics, especially if it’s something you haven’t studied in years. I still look things up on YouTube and Wikipedia and there is no shame in doing so: you’re in this position to learn and produce scientific outputs, so it’s much better that you’re comfortable with the topic.

I would suggest that for most people a PhD is generally more relaxed than an undergraduate degree. That’s not to say there isn’t work involved, but the pace gives you breathing room to understand the topic comprehensively.

If there’s one key message I’d like to get across, it’s please don’t ever be scared to ask your supervisor questions. You’re not on your own.

That’s assuming your supervisor is interested in supervising, which sadly isn’t always the case. Lack of supervisor support is one of the main difficulties I’ve seen students face (in other research groups I should add!). I wrote some tips here for choosing projects and supervisors.

How to Choose a PhD Project & Supervisor

Essentially as long as you are willing to learn, I wouldn’t worry too much about this aspect of a PhD.

Is a PhD intellectually difficult?

You’ve probably heard the metaphor about standing on the shoulders of giants, and it’s true that as a PhD student you’re building on previous work carried out in the field.

However there usually isn’t an expectation to make massive intellectual strides forwards. In reality you’ll probably be giving a small nudge forwards to a small area of the field. For some people this can be a relief and make the idea of doing original research much more obtainable, whereas for others it may belittle the entire idea of doing research!

The reality of the situation is that PhD students may be seen as a cost effective source of labour to advance science. Although we’re often working on projects with complicated lofty descriptions such as “nanoparticles impregnated with silver ions for cancer treatment” or “biphasic lubrication mechanics of soft engineering materials” in reality the practical side of them does not require genius level intellect.

Oftentimes you’ll be doing pretty menial things behind these grand topic titles. These tasks require you to know what you’re doing, but rarely will you have devised the whole thing yourself.

Fun fact: at my first job after undergrad, working at one of the most prestigious universities in the world, my boss would sometimes bring in her gardener to pick up any slack, doing the same work as me and some of the post-docs.

Of course you need to be able to understand the concepts behind what you’re doing, but I wouldn’t worry too much if you’re worried that you have to be a genius to complete a PhD.

So is a PhD easy?

In terms of workload and difficulty a PhD isn’t necessarily as difficult as you might think, so don’t be scared off. That’s not to say it’s not without challenges which we’ll now go on to discuss.

How a PhD can be hard

Of course there are differences between projects, supervisors and universities but I’d say generally the main things which can make a PhD hard are:

• Self motivation
• Looking after yourself
• Dealing with isolation
• Your ability to problem solve
• Fear of public speaking

Self motivation

Prior to studying for a PhD, your studies will likely have been structured by a timetable of contact hours, coursework deadlines and exams. Working towards a PhD is the first time you’re likely to experience fully independent working for extended periods of time. It will also involve work where no one, not even your supervisors, know all the answers. This can be daunting and I think this is where difficulties may stem from for many students.

A PhD is a long-term commitment so you need dedication to reach the end of a PhD.

By the end of your PhD you’ll have to demonstrate that you’ve contributed to your field with a thesis and/or peer-reviewed publications. This can be a challenge and without the regular undergraduate format of deadlines and exams, you may quickly lose focus. Regaining that focus and dedication is key to seeing your PhD through.

If this is something you struggle with check out my post on maintaining motivation during your PhD.

At Imperial we have two progress points throughout the PhD: one at 9-12 months (Early Stage Assessment) and another at 18-24 months (Late Stage Review). These formal progression checkpoints help by giving deadlines and a structure to work towards.

Solution: I believe one of the best ways to keep up productivity, and ensure you’re on the right track, is to meet regularly with the supervisor. I suggest meeting at least a few times per month. I do know some people who meet much less regularly and this can work for some people. However, I personally find myself chatting with my supervisor about far more than the types of things I’d want to ask in an email and this is where the mentorship aspect of a PhD can be made or broken.

In summary, working closely with your supervisor can make your PhD a lot less difficult.

Looking after yourself

It’s very easy to develop bad habits during your PhD such as:

• Eating badly and drinking too much coffee
• Getting stressed and working long hours
• Not getting exercise and sleeping poorly

From not cycling at all I've now cycled 1k+ miles in London, mostly commuting to @imperialcollege. Great way to get around with so many benefits. Started because of a free course by @RBKC & @Bikeworksuk w/ a refurbished bike! Few words about my experience: https://t.co/rGwSqomikD pic.twitter.com/joyVftxuVn

Solution: Remember that working longer hours won’t necessarily help your productivity. Instead take time out of your day for breaks and go for walks. Dedicate time to look after yourself. If you’re looking for ways to stay efficient, think of doing things like commuting by walking or cycling. I’d also highly recommend cooking your own meals to stay healthy (and save money).

Dealing with isolation

When I say isolation I really mean a few different things:

Owning your own project

Every PhD project is different, you may collaborate with friends or colleagues for bits of your work but you are the only person driving forwards your project.

This means that you may face problems other people in the research group or department haven’t encountered. Not only could this be isolating but it may also set your project back if you don’t mitigate the risks.

Solution: Firstly, don’t be afraid to ask people for help. Maybe someone from your group doesn’t have the answer to your problems but they may offer useful advice or know someone else in the department who may help. Coffee breaks offer an opportunity to informally chat with colleagues, which can both be fruitful for your work and your mental health: here is a nice Science article about the positives of coffee breaks.

Imposter Syndrome

As every project is unique it can be very difficult to tell how you measure up to other people. At times you may struggle to understand what other people in your group are working on, but this doesn’t mean you’re not cut out for it! Supervisors have a good idea of what’s required for a project when you’re applying: if you’re accepted you’ll more than likely be fine in this regard.

Solution: Don’t compare yourself to others. This is fruitless, especially when every project is different anyway. Make sure you understand your own project well and you’ll be fine. Having a chat with other students can be a good way to reassure you that everyone goes through difficult times.

Staying social

If I asked you to close your eyes and picture a PhD student, what would you see? Personally I used to conjure up an image of a fatigued student wearing goggles and trapped in a lab, rarely seeing daylight.

That’s not always a hundred miles away from the truth, but it doesn’t have to be the case. We’ve already covered how working such long hours can be counterproductive, but also putting yourself in a solitary position like this can be both demoralising and awful for your mental wellbeing. Please don’t!

Solution: Take frequent breaks, get involved with activities your lab-mates or department are organising: or organise something yourself. Find something you enjoy and can look forward to going along to, you can still join clubs and societies as a postgrad. Being isolated can make a PhD so much more mentally difficult: it doesn’t need to be!

Solving problems

You hear people saying that to be a good researcher you have to be inquisitive and questioning everything. These are certainly good traits to have which can make the work more meaningful, but at the level of a PhD student I believe it’s much more important to work smart.

To me this includes the ability to:

• Think on your feet
• Don’t be afraid to ask your supervisor questions
• Be forward thinking and catch problems early

Solution: Set up a framework to overcome problems and always think of ways to mitigate risks by having a Plan B. For example I work with people who’ve waited six months for consumables to arrive: if you don’t consider risks like this you immediately set yourself up for a less productive and more stressful experience. As before, I really do recommend meeting with your supervisor frequently.

Public speaking

I’m not sure whether presenting your work is a requirement for every PhD but it’s certainly an expectation for most. If nothing else you’ll likely have to present in your viva.

A fear of public speaking is very common and as such it’s a common PhD difficulty to tackle.

It’s completely natural to be nervous with the idea of presenting, however that’s not a reason to avoid public speaking completely. On the contrary you’ll only get comfortable with it by practicing. We’re fortunate as researchers to get regular opportunities to try public speaking.

I certainly still get nervous myself but would rather face the fear than shy away from it: plus you feel great afterwards.

Solution: Take opportunities to give presentations, whether it be at lab meetings, departmental events or conferences. The great thing with being a PhD student is that you get to practice with no expectations that you’ll be perfect. It’s much better to face it now than push the problem back later in to your career. I’ve written some tips for how to keep your presentation interesting.

Presentation Skills for Students: How to Stay On Topic and Keep Audience Attention

Some example issues you might have to overcome as a PhD student

Common PhD challenges

Now that we’ve covered the categories of common PhD difficulties here are some common day to day challenges:

• You need to use a technique or piece of old lab equipment and there’s no one to teach you how to use it
• You’re scared to ask for help because you think you should already know the answer
• You’re not getting the results from an experiment you’re expecting to see
• You need to write a code to do something and have never coded before
• You’re struggling to understand a concept
• You’re bored of reading or are losing interest in the topic
• You feel lonely
• You’re stuck waiting for something to arrive
• You need to create nice looking diagrams
• You need to build a rig or piece of equipment from scratch
• You’re worried about giving a presentation
• Your supervisor isn’t providing support
• You’ve no idea what statistical analysis to use
• You’re facing funding limitations, meaning you can’t do all the experiments you ideally would
• You’re struggling to motivate yourself to write a 100+ page thesis!

I’ve written a separate post covering a range of challenges I faced during my own PhD and you can find that post here: Overcoming Academic Challenges and Failure During a PhD.

Overcoming PhD challenges

It’s normal to face problems during a PhD. It’s how you tackle these problems that will be the defining factor in how difficult you find the PhD.

Part of the joy in completing a PhD is knowing that you’ve managed to overcome these difficulties.

In all these scenarios having a chat with other people will help. Even if other students or staff can’t directly provide assistance, most people are very friendly and supportive which will boost your morale.

I can’t overstate how useful scheduling regular meetings with your supervisor is. It’s so much better to face problems early rather than awkwardly have to deal with it six months later. I meet with my primary supervisor every week and we work together to set short-term deadlines for my work which tie in with the larger targets.

For problems outside of your supervisor’s remit lots of universities provide additional support. For example the graduate school at Imperial lays on courses for PhD students covering how to code, using reference managers, statistics etc.

Plus there are usually facilities for dealing with things such as stress and anxiety via counselling, student support and chaplaincies. Don’t make the PhD more difficult than it needs to be, these facilities are put in place to help you.

Has my PhD been hard?

Research

I’ve been surprised by how manageable the PhD has been. I wouldn’t say that any of the research work was particularly difficult, it has simply required dedication.

Good time management and taking my mental health seriously have helped a lot, as has considering it a full time job. Slow and steady wins the race. Simple steps like always having a backup plan to mitigate the chance of getting stuck if things go wrong has served me well.

Presenting

I’ve never been a fan of presenting but have learned to expose myself to it in an effort for self improvement. Of the five conference presentations I gave during my PhD, I won prizes for two.

Remember that you may lack self confidence but how you come across to other people may not be how you perceive yourself: this can be very uplifting. If I can do it so can you!

Thesis-writing

I’m currently in the process of writing up a separate post dedicated to my experience of writing a thesis. In summary, for me personally, it wasn’t anything like as stressful as I was thinking it would be.

I gave myself approximately six weeks to write most of it. Mine was 190 pages in total which may sound daunting but I actually only had about 120 pages of proper content and it’s all with 1.5 line spacing. Each chapter was only about 20 pages which sounds much more manageable and really isn’t much for 3 years work!

Things which helped me included:

• Having already written up some results.
• Using figures I’d made for presentations.
• Not expecting it to be perfect.
• Setting myself tight deadlines. I gave myself two weeks to write the introduction, literature review and discussion chapters.

Some of us PhD students make things more difficult than they need to be, trying to make everything perfect. I’ve heard some staff say “good enough is good enough” which I’ve found a useful mantra.

I recommend not spending too long on the thesis because:

• Papers are what count, put your energy into them instead.
• There is no point trying to second-guess what your examiners may want to see, you could spend months deliberating and they’ll still potentially have corrections to suggest.

Viva

I was a bit nervous before my viva, which is normal. I was confident in the work I had done for the PhD, but was actually more concerned about being asked any theoretical or technical questions you’d be more likely to encounter in an undergraduate course.

Although it lasted more than five hours, mine was a supportive environment, mostly a discussion to give feedback to improve the thesis and publications. Remember to be honest and be reassured that you know your work better than anyone else.

In summary, how hard is a PhD?

• Most PhDs are not intellectually difficult but they do present other challenges
• How hard you may find a PhD depends on your ability to self motivate, look after yourself, deal with isolation, problem solve and master public speaking
• Everyone experiences challenges during their PhD but it’s how you confront those challenges that matters
• Make the most of your supervisor for support and guidance
