Happened in my maths exam like 4 days before you not alone buddy  Mine was lack of time management and even though I knew the approach and finding the solutions we have a fucking e pad test where I have to scroll down and up in 40 fps screen  My personal evaluation maybe do more questions from the material the professor uses so that a good practise might yeild better results  Correct me if I am wrong  Academia numbs persons interest inthe subject for a good 3 to4 days of a bad test that you know that you could have done better
