In first year and second year my biggest mistake was not having a meticulous exam plan. I developed one in third year and ended up averaging a first. However, I now know how to plan in great detail to take things in so the learning curve itself will be a great tool to use in life.
My exam plan in third year.
Firstly, I'd get all the material for the exam and create a mind map of it all. I'd include key words and acronyms and then branch off with definitions. I'd then expand this into typed up notes and put the mind map at the front with the stapled notes behind.
Secondly, I'd create a presentation of the key points and read over them in my mind as the presentation went through. As the presentation automatically looped through I'd start recalling terms with more ease due to the repetitive nature of the task.
Thirdly, on the eve of the exam(s) I would sleep early and then wake up around 6am. I'd get a good breakfast in and then spend 2 hours revising before heading to the location of the exam. I'd take my notes with me on the bus and read through them. I'd then look at the mind map before binning it and entering the exam room.
Finally, once we were allowed to start writing I'd turn to the back of the exam answer booklet and spend the first 5 minutes reproducing the mind map I had just visualised from memory in the back of the booklet. At this point I wouldn't even look at the question paper. I would be in a state of focus to ensure no detail was forgotten. Once the mind map was complete I would look at the questions and get on with them.
As exams were often 2 hours long I'd deduct 5 minutes for the mind map, 5 minutes for reading questions and then 5 minutes for checking over. I'd spend the entire time there and never leave early. I'd then have 35 minutes per question as we had to answer 3 of the 5 available questions. Of course, with longer exams you'd split the time to suit.
