I missed studying for O's. Seriously. I miss searching my house for my Chem notes, lugging my English file to the library, drawing on my friend's textbook instead of reading Bio, practising papers after papers for Amaths and getting very angry when I couldn't get the answers. The whole process =(
o level is up to you to decide your future..if you feel like studying then study uh. no one wants to get bad grades after paying a few hundreds just to sit for the paper.
