The Blue book

I don’t know what’s wrong with me but my math and Writing scores suddenly dropped pathetically in my last mock test (practice test #8 in the Blue Book). I couldn’t answer some math questions even after checking the correct answers, which never happened to me before. I’m wondering whether the real test is as hard as those in Blue Book, and does anyone have a collection of uncommon and very tricky Math & Writing questions?

Those tests in the BB are very old, and from what I’ve read on these forums, real SAT scores tend to fluctuate 100 points or so. Only 3 BB tests were actually administered, the rest are just CB creating questions for practice.

thanks @Evangelise ! Do you know which ones are administered?

The first three were administered, I think, because the grading scale are actually precise w/o any ranges.
