Not gunna lie, I am SO glad I cam across this thread!! I’m taking Biology, Chemistry and English Lit AS (I dropped psychology pretty quick because I was soooo stressed). Just did my mocks and got a D in Bio and a C in Chem. I worked soooo hard for them as well. I want to do medicine too so I understand your stress completely!! I get really stressed and overwhelmed easily. I feel what I’m doing at the moment revision wise isn’t a quick fix for tests at the moment so maybe don’t focus on these mini tests and grades! Just try and focus on the end goal because I’m sure you’re doing enough work because for some people it takes time for things to click (if that makes sense) but mannnnnn I feel you rn. If you ever need support and what not, message me! Id be so glad to help and it would probably help me too!
