THAT'S IT FOLKS!

Quiz solutions now on Vista, make sure you use these as practice for the upcoming test.

Unfortunately, past papers are quite sparse and not entirely relevant. So once you're through the tutorials, work through the relevant examples in Chapters 40 to 43 of the textbook.
There's also some (but not many) relevant questions in Papers 2 of some recent summer session papers.
Papers and solutions are available here.

Here's the formula sheet you'll be given for Test 2
Note the error in the Fermi probability - the "-1" in the parenthesis should read "+1".


GOOD LUCK!
