Step 1: Get the right books
Instead, you have to buy the Official SAT Study Guide published by the College Board. This is the ONLY book that has 8 genuine real College Board SATs inside. Why does it matter? These questions are written using a special formula, and the right answers ALSO follow a special formula. You need to practice with the real deal, not a simulated SAT-like exam
You can get this at your bookstore, but your best bet is on Amazon.com:
Step 2: Get the second right book
Thankfully, there is a book written by a teacher who has personally taken more than 30 SAT's which tells you EXACTLY why each answer choice is right.
Also on Amazon.com, it's the Official SAT Study Guide Solutions Manual:
Step 3: Get the third book
Or, you can purchase the Home Study Course from SAT Solutions.
