Yes. You work at a rate of roughly two chapters per day (therefore reading all the content within a week), and then spend about a week practising questions from that module and doing past papers. This should take you 12 weeks (3 months). I assume you're half decent at maths, so you should end up with a C minimum, most likely a B, and an A if you're good/lucky. The one week of practising questions is essential for you have to the required preparation for the exam. Another important note of interest, only do miscellaneous exercises and past papers (you only have a week to practise). You can pursue all topics that interest you at your own leisure after the exams. You might think I'm talking crap, but I did it, and I'm the laziest person I know (my motivation was to not suffer a bruised ego from doing crap).
However, considering your situation, I think it's just a waste of time.
