having not enough time for revision can be disastrous. but having too much time is also a not-so-good thing for me. when i have no time to study. i will half study half think of what will happen if i no time. so efficiency droppped. when i too much time. i will slack until last minute den start to stress out and in de end do nothing as well. just like the 4days long teacher's day break. 4 WHOLE days to study bio. and i only completed 4 chapters by the end of it.. wth!
