studying the night before is not a good idea.
u should do all the exercises and homeworks daily maybe at least twice
and stick the important formulas like sin@=cos(90-@) on your wall or somewhere u can see
that's wad i do...
but try not to drop the 2U maths!
well, u can also study with me
but honestly, i m not good at maths but i got 90+ in tests ..
