Thank you for the tips! I like how they don't deal with studying the material, but rather address the feelings, the comfort level.
All of them sound like they could really make a difference. I have never even thought of taking a test with earplugs in! I agree that the quiet would probably really change perception, and it would need practice to be effective rather than distracting (hearing your own heart beat!).
Not studying the day before is something I have never been able to achieve, but hearing how it can really make a difference, I will strive for this. I have been for my Master's, and I can see how not having to cram brings confidence. Believing in yourself is also really important not to forget. In my country, people say about upcoming stressful situations 'You can't breathe in enough before death.'
What's coming is coming, and last day of studying like crazy is probably better spent trying to relax and mentally prepare. Thank you!
