Are Barron's book exams accurate?

So I recently bought Barron’s AP books for every subject (using an outdated AP Psych so I ordered a new one as well) I’m doing this year and I probably should’ve asked this before hand but how accurate are the exams in the book? I feel that I know the material for 2 of the 5 classes well enough to get a 3-4, and the other 3 well enough to get a 4-5. I just want to know if my score on the Barron’s books are accurate to what I might get on the real thing.

The tests I’m doing are: AP Psychology (first semester/ don’t remember everything), AP HUGS (first semester but remember most stuff well), AP Stat (first semester/need a lot of review), APES, and APUSH

Barron’s books tend to be dense in content. If you like brief and straight to the point, Princeton is a good choice. However, Barron focuses more on details so it is good for learning in advance and cramming.
