Improving CARS, C/P, and B/B in under 4 weeks (testing 1/23)

So I've done FL 1, 2 and 3 and averaged 125 on CARS and 127.5 on both C/P and B/B.

For CARS, I always feel confident after the section but end up scoring around 39/53. I understand the passages pretty well but almost all my mistakes come down to the 50/50s. Would love to hear advice from people who were able to improve from 125 --> 128+ (I test on 1/23)

Not sure how to get over the plateau of C/P and B/B. I completed both SBs and averaged around 75%. Really want to hit 130 and I think my content knowledge is strong
