maths is through constant practise one..
i got E for A levels prelims, and i did maths overnight almost
everyday. I will start from 7pm after dinner, sit at my desk and do
do do practise practise practise till 7am.
i think it continued for a few weeks, den in the end A levels I got
an A for Maths C.
I did the same for O levels too. I finished the whole 10 yr series
twice (for E maths), and i also got A1..
so, just continue to practise hard... Prelims usually harder than
actual exams.. dun scared k! Jia you.
