I took the November math lvl 2, and it definitely took me by surprise. Maybe I underestimated it, or maybe it was just that hard, I can't say. But I found the test VERY different from the ones in Barron's! There were two money/interest based questions and those topics weren't included in the Barron's book. (Idk about you guys, but I bought mine from India, so the topics might be different, I guess? lol). I got above the 750 mark in all my Barron's tests and even the Sparknotes online tests. But I think I had left almost half the questions in the real thing. Expecting my scores today, they're going to suck.
Good luck to you guys though. Practice more! that really helps.
