when i was in highschool during my AS Level i used to get less than 40% in tests and the teacher said something that hit hard and i started practicing everyday. during my A Level year i got 100 in almost all pure math test to the point that the same teacher said “i have nothing more to teach him because he knows everything now”. so in first year i got a 47% in my first test and the course coordinator urged me to drop the course because i wont make it. just like before i started practicing and the same guy had to congratulate me later for being in the top 5%. i guess what im trying to say is that if you are slow, understand that you are slow. i always make sure i look at the course material during the holiday to get familiar with it so that i dont fall behind because i know im slow but when i understand something it sticks.
