I have recently marked my first lot of final exams ever. Surprisingly, I found it quite fun. I learned a lot from the experience, not to mention that students taught me a few new (made-up) theories on the subject matter.
After reading through more than 100 exams, I realised that one tip I had received during my university studies was not common knowledge. So I decided to share it here fore you now, so that it may help you during your final exams.
