Chem HL Grades :(((((

Guys, please I literally need help, like godsent help because I am literally failing chem HL. In my last mock I got a really high 5 and got predicted a 6. This helped me with my medicine applications for the UK and Ireland. However, I just got back my second mock and its a fucking 4!!!!!! Like- now I'm gonna get predicted a 5 and I'm scared that all my universities are going to reject me because they need 7,6,6 at HL. I have a 7 in business, and a high 6 in bio which I can get up to a 7. BUT THE MAIN PROBLEM IS CHEMISTRY!!!

I really need advice on what I can do to get my chemistry grade up. I already have a tutor and practised a few past papers before my mock exams but nothing seems to work. If y'all have anything please help me 🥹
