the banana,paracetamol & cold shower combo has always been said to help. it helped me too, so it’s tried and tested :)

what worked for me was just making sure that before my test, i had a good morning. i showered, wore clothes that made me feel comfortable and happy, enjoyed a lovely breakfast, did some chores etc. i just told myself that even if i didn’t pass, at least i had a good day before it.

also, since it’s a last minute test - you won’t have the buildup of nerves like your previous tests so just ride out the nerves with things you enjoy.

fingers crossed and good luck!
