If you havent been studying, i think you should. I thought i could handle everything after i celebrate my birthday, but trying to recall everything at that time is probably too late. I just did my own studies on alcohols and phenols and it gave me a real headache. So piece of advice- better prefect what you learnt otherwise it's going to kill BIG time. Time- something which you dont have much off.
and i found a photo of my secondary one class while studying. (more like i found it when i was searching for more foolscap paper) How innocent we looked back then. Everyone looked so young, so pure and totally unaware of what the world is carrying for us back then.
