Hey guys, I'm at university at the moment studying computer science but I'm also looking to learn maths in my spare time. Unfortunately maths is a terrible subject for me and I struggle immensely with it.

At GCSE I got an E in maths and I have forgotten how to do even the simplest things such as fractions and percentages. I just really struggle to learn to the rules and sequence of steps you need to take to work out questions that have more than 2 steps.

A friend told me about a CD I can download that he used during his school GCSE revision but I forget what it's called. Once I learn everything on that CD and can effeciently answer questions without having to refer to anything for help, what should be the next step for me?

Btw if anyone can remember the name of that CD that would be awesome
