But the study help team will have no idea what level of mathematics you're at (they answer questions from anything ranging from pre-GCSE problems to degree level ones) and they aren't able to teach you an entire syllabus. The usual format of the study help section as I understand it is that you show what work you have currently done on a problem, and they will advise you on whether that's correct, guide you to the correct method if using the wrong one, and try to prod you to the right answer if you're on the right track already (or after this).
If you need general help with maths you may want to try searching on youtube for videos relevant to your level. Khan Academy may be worth checking out as they have videos on a variety of topics across a range of levels (up to degree level, from fairly basic school maths). mathsrevision.net (now moved to a new URL, should redirect but I don't know what the new one is offhand) has some resources for GCSE and A-level, although it seems poorer than previously. BBC Bitesize will have some resources for GCSE level or similar maths. paulsonlinemathnotes has a lot of material ranging from "advanced" school maths (A-level Maths/Further Maths) to a wide range of degree level topics. Physicsforums also has a lot of help/advice regarding degree level maths and recommended textbooks for self studying. The Chicago Undergraduate Mathematics Bibliography has a lot of useful advice on textbooks for undergraduate and masters and early PhD level maths, both on commonly prescribed books and less typical examples.
