Surely you would have learnt how to use the finance solver...? :S I am getting the impression you have not even learnt this module. Why are you attempting to learn it?
No I didn't do Business-related mathematics in school. Did you? I wanted to check it out (out of pure interest) + I'm thinking about doing all 6 modules on exam 2. So once again, where are you getting this 'financial solver' stuff from?
Out of curiosity, why waste time doing 6 modules when they mark only three (probably the first three)?
I'm pretty sure they mark everything you write down and then give you the 3 best scores out of all the modules you answered. At any rate the first 3 will probably be my best 3.
