UPCAT review help with math

Hi guys! So nagBT aq, and i started self studying last week kse narealize ko i need to lock in na pala hahahaha. so nagstart aq magstudy sa manual, and then i started doing practice tests. Pero the problem is dko talaga alam ung mga sagot sa questions when i do practice tests, almost always end up chatgpt or googling the answer. What I do is practice writing and remembering the solutions, and then when i do practice test again i try to mark ung mga questions na nahihirapan aq so i can practice the solution again.

I know na practice tests are the best way talaga to learn mathematics, pero iniisip ko lang kung im doing it wrong kse i feel like im going too slow… do you think i should just go back to relearning each fundamentals topic or continue practice tests huhu…

also asking for tips or study routine po for upcat, thank u po!
