Any help/ tips on how to increase grades and is there hope?

Hi guys!
I’m not doing my best on my a levels (Sociology, Fine art) and btec (Health and social care) rn☹️.
My predicted is acc SO unbelievably low too (CCMerit) and I rly need (DistinctionBB-BBMerit) is there any way possible I can achieve this as of my actual exams next year or boost my predictions now?
Plus can my personal statement outshine my grades at all? Or will my uni choices solely focus on matching grade requirements and predictions?
I’m so stressed and feel like it’s so out of reach for me as this is the first time I’ve been given a set grade I’m working towards, otherwise if I had known this is how I’m working currently I would’ve started working towards higher, I’m just so full of regrets and don’t know what to do now. Y13 is definitely not easy 💔

Please don’t worry - universities review your application as a whole and consider your qualifications, skills, and experience. This means your personal statement is just as important as your grades. Predicted grades give universities an indication, but your actual results are what ultimately matter.
