hehe, my fav question
not that hard, u can do it easily.
i will give simple tips such as ..
- study each subject a day, for some time (like 1 day math, 1 day IT, and try it for like 1 hour) (this could be a timetable)
- while studying, try to concentrate, try to take less breaks.
- understand the concept while studying
- if u like some chapter/ or if u like any part, u can practice them in pastpapers (so u get more better in it)
- also to test, if u understood any concept or not, try practicing past papers (and check them from mark scheme which can be found in freeeexampapers.com)
Take the advice calmly and try to implement it.
INSHORT - DO how much ever PAST-PAPERS u can...
First solve the past paper... then check the mark-scheme to correct it..
this will allow u to know how much is ur average..
EXTRA STEP--> If u get any answer wrong, erase it and write the correct answer and keep the past paper, this will help u while revising =)
