Hi there equinox_code
I am also going to the phase 2 assesment on the 18th, hope to see you there. I found the following site
http://www.thatquiz.com/tq/practice.html?fraction very helpful for brushing up on some maths questions on fractions, long devision etc. If you need to revise techniques
http://www.bbc.co.uk/schools/gcsebitesize/maths/ is really helpful and explain quite well the methods you need to use (been 5 years since did A level maths, come back to earth with a bump
)
