Hello
I've been insanely practicing for the SAT and I have like 1 practice test left and it's not even completely empty. Is it worth it buying another book and starting over? I don't really want to erase everything.
That's entirely your choice. If I were you, I'd try to squeeze in a little more practice if you're that passionate about the SAT. So yes, you can always buy another book.
I think I'd try another book, not BB, since you're done with that one. I like Barrons, because the questions are harder and more challenging than BB, which makes the real SAT questions seem easier.
Dont' use other books not made from collegeboard!!! Only use CB Because THEY are the ones who write the test. Any other book won't give you the correct practice!
If you need more CB tests, get Released ones! That's what I did. I got like 20-30 released tests that I practiced from
For anyone wondering, I'm sure this will be helpful. This site: satquantum - satpracticetest
gives explanations (videos) to all the questions from the released tests.
