Papers!! Papers!! Papers!!

It is the best method of highlighting gaps in your knowledge.
Don't be afraid to make mistakes!!!
Always document your mistakes and keep note of them for future revision.

Watch your time
It roughly works out at 90seconds per mark when answering questions.
Don't get bogged down if a question is difficult/weird!!
The IB can be sneaky, don't panic if you see a sneaky/weird question! #sneakyIB
