which is fairly comprehensive, although perhaps it goes into too much detail, and so it's hard to know exactly what to study.
I'm doing World History this December, so have plenty of time to prepare - should I get the Barron's book or another prep book to supplement the above one, or not bother? (I already have the Official Guide To Subject Tests).
The book you have seems pretty detailed, just based on the excerpts. Go over the book first and then take a practice test. If you don't do so well on the practice test, then I recommend Barron's AP World History review book; it is also really in-depth and will serve well as an SAT II World History prep book.
