Does anybody have a way of remembering all the different equations in P1 and how to use them ? really struggling as maths is not my best subject.

You get given the equations on the sheet! Put them into formula triangles? E.g a=bxc it goes a
bxc cover up the one you want to work out. Or a trickier one: a=b divided by c (a=b/c)
it goes: b
a x c (cover up 'a' to get b over c)

Hope it helps!

Just to make sure, look at past papers for your exam board and see what equations they give you, you don't want to go in expecting formulas they don't actually give you!

Practise is probably the key so that the equations stick in your head.

Most of the complex equations are given at the front of the paper.


See if you can make up a rhyme or a triangle.

For example in biology to remember the magnification formula I just remember AIM

Actual = Image/magnification.

Most are given to you? But yeah formula triangles work a treat; as long as you know (or given) one way to write the equation you can make a triangle and cover the unknown up to give you the formula you need eg Distance = speed x time, and the 'times' equation always makes the base of your triangle and the other goes at the top.

Don't you have a formula sheet?

I would practice rearranging equations since this is an essential skill and it cuts down on the need to remember lots of stuff since you can prove them while you work.
