Need help with SAT Critical Reading

I am preparing from Princeton books still seeing no improvement. My acurracy is around 60% on the reading passages and even after practicing, my score remains more of less the same but in maths Im seeing a lot of improvement. Btw Im international student. Please Help!!!

I highly, highly recommend the Khan Academy SAT practice. It’s free, you can link it to your College Board account, and you can track your practice. It was one of the few things I did to prepare for my SAT, and it seemed to really help.
