Doing a PhD is an incredibly daunting task. Normally at least 3 years, there are some challenges that you are almost certainly going to have to face. Below we look at some of the biggest (and most common) problems that PhD students encounter. If you are considering a PhD, or just beginning one, advanced awareness of these stresses may help you overcome them if you ever have to make their acquaintance (don't worry, we have our fingers crossed). Plus, knowing that they are frequently experienced and nothing out of the ordinary will hopefully provide you with some comfort.

Once you've handed in your thesis, you still have one big challenge to overcome before you're finished with your PhD: the thesis defense. This is an opportunity for you to present your research publicly and to answer questions about it from your thesis committee. The process can be tough going, especially if you've never had to do anything like this before. That being said, there are a few ways to make sure you survive – and even perform very well in – your thesis defense.

While pursuing a graduate degree is undeniably interesting and challenging, tuition fees and other costs associated with studying have been getting higher and higher over the last decade. This has lead to plenty of students questioning whether the expense in terms of time and money that they will have to put into obtaining a graduate degree is worth it.
