Computer Science Maths Test Content

I've been called back to complete an hour long Maths test as I didn't get the required B Grade at GCSE and I wanted to know what kind of things might come up? It's been 2 years since I've studied maths and I can't really remember much.
The test is on Jan 5, though I'll probably move it to a later date.
Any help will be much appreciated, and any brief GCSE Maths notes would be good, too.
Thanks

I have an exam at the end of April can you clearly clarify of the topics that are likely to come up.

Topics that came up for me:

Logarithms
Simultaneous Equations
Deriving

Ahhh i cant think of any more i'll get back to you

Has anyone got a list of topics that came up recently for the queen mary maths test for comp sci. A list would be helpful not 1 or 2 topics.
