i take notes on my books because i have a hard time listening to boring professors and writing down their boring notes. this is horrible because it takes for ever to write down things about everything. once im done i feel great. some times i read them over again and they day before the exam i read them alot like 10 to 20 times.
i dont recommend this method, but it works for me even tho its tedious.
im also looking for a better method that would help me out. ive tried plenty but none so far have helped unfortunately, so im sticking to this till i find somethign else
