Put literally EVERYTHING in your diary. And I mean everything. The examiners need to be able to see all your mental processes and how you got to the final product, so just put everything in there. Doesn't matter if you finish one book in your first year, just go into another one.
Choose artists from a range of time periods and cultural backgrounds for your comparative.
Think a lot about your exhibition and how you want to present it, and if that influences how you want it to be seen. Try to make it personal.
