Question 2

The questions are written using the official Dundee lectures, so you might find it useful to have them open in the background in case you get stuck.

Question 3

I write the questions based on what I think the important facts are, but not everything is relevant. Don’t waste your time learning tiny details.

Question 4

On the other hand, this isn’t everything you need to know - back it up with stuff from tutorials, other people’s questions, Youtube videos, Oxford handbooks etc.

Question 5

There’s a good chance that older decks will be inaccurate (lectures and guidelines change year to year) so I’ll try to update them in the future.
