Hey
I totaly understand how you feel, my dad's a maths freak and can't grasp why the whole world can't learn 4unit maths in grade 2

hehe exgageration
But my suggestion to you is to master the basics before you even look at the harder questions - make a list of formulas, memorise them, practice easy stuff. When you feel like you're making progress, start adding in difficulty and most importantly don't freak out! Depending on what level your at (general, 2uit, 3unit, 4unit) I can give you a hand...
Good Luck!
Anna
