barron's math 2 vs real things

i’ve taken four barron’s math 2 practice tests (710, 690,730,710), and I just want to know what I should expect to get on the real math level 2 test. Thanks!

To tack on to this, I got three tests, (630, 650, 780). I’ve been told to add ~100 points to that score, but I’ll post here for confirmation.

Yes, I’ve heard about adding about 100 to your Barron’s score and that will be your real score.
