<p>In your opinion, which SAT prep book/company is best for improving a low (500ish) CR score to north of 750 in 2 years?</p>
<p>Get the Bluebook and do EVERY SINGLE problem and REVIEW EVERY SINGLE PROBLEM. Critical Reading isn’t something that can be taught, it requires long-term reading habits and general insights. Look up SOAPstone and do it for every reading passage you do. The SAT CR is quite similar to the AP Language & Composition test. Also memorize a lot of vocab words.</p>
