I did a maths & physics refresher course and found it to be a waste of money. It cost £200 + VAT, and it started off with 'do you know how to add'?. We ended skipping most of the course, and settled on a few of the things to do with pythagoras, and trig. It was supposed to be 10hrs, but we were done in about 3. As for the physics bit, there wasn't much in it, as I recall. Thinking that I paid £2000 for my ATPL, it was a real waste of money.
The book is also massively over priced for what it is, I don't recommend it. Go and buy a cheap O-level revision book instead.
Your course, if it's any good, will give you all the formula you need to know. It should also contain a refresh on some of the physics courses.
