USING OLD SAT BLUE BOOK BETTER(FOR SCORE)??(1ST EDITION)

Test Preparation
1

I own the 1st edition of the SAT blue book, I wanted the newer one, but a friend told me he prepped with the old one and got +400 points. Should I upgrade?Is the 1st edition useless???

2

both work, but 2nd edition is much more reliable.

if you have the time & money, get both. but I recommend focusing mainly on the 2nd edition.

anyone with enough practice can increase 400 points.

Possibly, but my answer is closer to No.
Older blue books are much easier than recent editions. However, CC MIGHT recycle old tests.
