There are seven theorems for you to discover and prove.

  1. Go to this page to discover seven hypothesis.
  2. Go to this page to see the seven theorems summarised.
  3. Come up with seven proofs and put them, with your name, as comments below.

http://www.khanacademy.org/ and http://patrickjmt.com/ have many videos relevant to IGCSE math. If you feel a topic is missing in the list below, post a comment or send me an email (jannordgreen@gmail.com). Likewise if you feel one of the videos should be replaced by a better one.

Note: The list below is a modest start. It will be added to shortly.

Note 2: You can sign in to the Khan Academy to test your skills and see recommended videos. If you want me to see how you are doing add me as one of your coaches by entering my email address (jannordgreen@gmail.com).

Note 3: If you find a good, free video you want included, please email me.
