Is it still possible for a academic comeback?

I'm trying to make a comeback as I'm struggling in most of my subjects. As of right now I have a predicted of 35 Chem HL(5) Bio HL(5) BM HL(6) Math SL(5) English SL(5) Spanish SL(7) and 2 points from my EE TOK essay and exhibition. and I have until May to lock in, because for biology I understand the key concepts but as fluent as IB would want. Chemistry I feel pretty confident in and I feel like I could get a 6 same goes for BM. But the hardest part for me is spanish math and english as of right now if I would take the math final I would at best get a 2 or 3, for english I feel like I would get a 3 or 4 maximum and for spanish I am not sure how to study for it. If you guys have any tips for my subjects and how I could reach my predicted or even a higher mark.
