For revision it's best to take small amounts in over a period of time. Don't rush your learning. Just concentrate on remembering the key areas in what you're trying to excel at. If you try to remember too much stuff all at once, you are bound to get stressed. Try those things that calm you down, perhaps whilst revising. Make sure you're comfortable also when doing it, and take your time. Monday is a whole 6 days away. 6 days is better than nothing, it's not like it's tomorrow after all
Trust me, don't worry about everything. You will do fine, just know you will and have faith in yourself. You will do good, believe me.
Anyway, I have to take off now. See you later sweetie ^_^ Take care, stay safe and relax. x
