Sorry if this sounds extremely patronising but I can't think of any other way to word it: If you're finding the maths tricky, head into the college library and search through all the maths books until you find one pitched at your level and which is written in a style that you can understand. Sometimes a single chapter in a large book is best, sometimes a small book which just concentrates on one topic. It may take quite a while to find the best book but it will really be time well spent. This approach got me through complex numbers, vectors and calculus at uni. Hope this helps. - John
