Khan Academy
As I think I’ve mentioned here before, I’m studying some maths over the summer – Calculus and Linear Algebra 2 (MATH2000). I’m enjoying it, and I’m pretty confident that I can succeed in this course.
There are two things that could make me fail. One is if I don’t simply put in the hours of practice required. It’s been my besetting sin in maths classes all my life: I completely understand what the teacher or lecturer explains in class, but then fail to put in the practice so can’t remember it when I get to the exam.
The other is the fact that I’m coming to it pretty ‘cold’. Most of my fellow students are in the midst of studying maths or science degrees, and have been immersed in this stuff recently. I’ve done most of the prerequisite stuff, but some of it was almost 30 years ago, so I need some revision.
That’s why I’m very grateful that Matt pointed me in the direction of Khan Academy. It’s a non-profit organisation that produces a heap of YouTube videos explaining maths, science and other concepts, from the very simple to the very complex. The explanations are very clear and detailed, and there’s an absolute heap of them. I’m using them to revise integration at the moment, but they’ll also be helpful for differential equations.
So, for all your maths revision needs, I can’t recommend Khan Academy highly enough.
