Barrons AP Music Theory

I’ve been using the Barrons book to self study AP Music theory for a while. While I feel as though my concepts are definitely in check, section A of their practice test got me a 26/42, and I’m aiming for a 5 on the test :/. For anyone who used Barrons and took the test, how does the actual AP Music Theory test compare to Barrons?

The actual test is a zillion times more difficult.

More difficult in the MCs or FRQs? Or is it both?

Both
