Thanks Ari, Alpha, and Crooked, i know the A-levels is much harder than the O-levels.
As i said i only have 7-8 months to prepare and the subjects i will be taking are:
Chemistry
Biology
Mathematics
English
and maybe physics
Do u think if i take these subjects they r doable in the time span that i have?? I might get some teacher help but mainly i will be studying on my own.
