Video Tutorials

While the Internet can be a great source of information, it also contains a lot of rubbish. The challenge in making good use of it, is to find the useful stuff and avoid wasting time or being misinformed by the rubbish. The following links are ones that I think might be of some use to second level maths students. Please feel free to e-mail your comments as to whether you found them beneficial or not. If you e-mail me other links of items you think suitable for this section I will consider adding them to this page.

But be warned. Spending hours upon hours at a time looking at video tutorials will do you no good. It will just waste a lot of your valuable time. To get benefit from it just look at one or two at a time to gain an appreciation for a particular topic, then think about it and try and work out a few examples for yourself to be sure you understand it properly.
