Hi,
Omg I was in the same boat. I did alevel chemistry and boy it's hard!! I'm at first year of uni now doing a foundation year for optometry. (Im hoping i pass the foundation year to get onto it!) And I understand you completely. I literally worked my ass off for chemistry. I did everything yet I got a grade D at A2 (needed a B but they still accepted me, I really don't know how!😅
I worked so hard and use to get headaches and nosebleeds and everything. My teachers knew I worked extremely hard but it just didn't reflect in my grades. I was consistently getting D grades. (At AS it was U's!)
My teachers felt sorry for me, but told me all I could do was work hard and I did yet despite my grade I got into the uni I wanted !
My advise would be just do your best, I did and look at me now I'm still doing what I wanted even though I didn't get the best grade at Chemistry. And I was one of the students who didn't do Alevels maths as I hated maths. (That explained the struggling!!)
Just do PLENTY of practice papers! And understand the mark scheme. I LOVED organic it was inorganic that I really didn't like, again probably because of the maths.
I made flashcards on the content (365, yes I counted them haha!)
Just work hard and attend all support groups, in my school we had "session 3s".
Ask your teachers what you can do and the advise they can give you to improve. (My teachers, hands down were extremely helpful).
And ask your peers to help you and watch YouTube clips, my teacher was obsessed with MaChemGuy!
What exam board you doing, we did OCR A.
Feel free to private message me if you need any advice etc.
I honestly wish you all the best, please don't give up! You can do this!!
