Hi,
Do you know whether there are any revision or notes websites for mathematics (especially HL)? Something like bioninja, because let me tell you that that website is saving my biology grade, but my maths grade needs help even more...

A very useful youtube channel for calculus (especially the option) is professor Leonard. These aren't summaries or revision videos though, they're full on lectures. Also, the Cambridge book is pretty good. Something that used to help me is watching people solve questions on youtube (just search for IB math HL questions on youtube).
