Working towards exams can make us feel under a lot of pressure, especially at University. There may be no choice about taking exams but there are definitely things we can do to reduce the stress that can come with them:
Standing around and joinging in with the exam post mortem can often be discouraging. Don't spend time worrying and criticisng yourself for what you think went wrong. Congratulate yourself for what you know you did right.
Reward yourself for your hard work. Do something you enjoy. Let the stress of that exam go, especially if you have more exams coming up in the next few days / weeks.
