Crossing out multiple choice answers, making notes for questions, marking questions

Crossing out answers that we assume are incorrect could help when we're reviewing

Making notes about questions would be useful when reviewing so that we can write what we did wrong and how to prevent the mistake from happening again

Marking questions (during timed practice) that we're uncertain about with a small symbol could be useful so that we can review them before our time is up and return to see why we got the question wrong
