How can I improve from 126 --> 130 on C/P and B/B

I've been practicing heavy with upoop and aamc qbanks for the past month and a half and I've been stuck at between a fluctuating 124-126. It's genuinely pissing me off and I don't know what more to do to improve. I miss an approximate 15-20 questions in these sections each time and it's simply frustrating. Any and all tips would be so so helpful, please.
