I have a schedule laid out for my BB test, and for the review of them. With CR (my weakest area), I am struggling with the timing, it’s taking me a lot time to eliminate the wrong / justify the right, when down to two. What I am looking for is more practice material, which effectively mimics test questions. The CR was good for this, but didn’t last long in the way of examples. The CB quizzes were exact examples of what I am looking for. I made some nice improvements using it.
There are 4 free tests available online that aren’t in the Blue Book. If you still need more, you might consider purchasing the Official SAT Online Course from College Board. That’ll give you a bunch more tests.
