R&W is so hard for me (especially Reading) because English is my second language and this is just my second year living in US. I got 600 in May and I really want to get a 700. I worked so hard during summer. I did not attend any SAT class but self-study it with Khan Academy, Barron’s, and PR. I’ve just done two CB practice test and still got around 600 which means there’s NO IMPROVEMENT AT ALL. I’m running out of Khan Academy’s questions and there’s only one CB’s practice test left. And I feel like Barron’s and PR are so much harder than the real one…Oct 1 is coming up and I’m a senior and I also have to take Subject tests in November, which means the upcoming one is my last or second last chance…I don’t know what I can do right now
Ivy Global 2nd edition is probably the next best one. Not perfect by any means, but decent for practice.
