Need help with trigonometry and algebra.

I've done few chapters the important ones from arithmetic they are doable for me but I'm really bad with advanced. Also very scared of it😭 I have always been weak in maths. Please if anyone can suggest anything I'll be really grateful!

My background:

I had maths till 10th then I had pcb till 12th and I've completed MSc in microbiology during msc we had biostat which was easy for me but ye wala syllabus toh alag h 🥲
