SAT World History

I’ve been self-studying World history using 3 books

  1. Barron’s World History 2013 -Marilynn Hitchens and Hedi Roupp (5th edition)
  2. Barron’s World History 2015 - William Melega (1st edition)
  3. Holt (I don’t use this unless I need further explanation or what not)

How do you recommend I study for the WH test?
Which of the 2 Barron’s book is easier/ more reliable to study from?
Should I try studying the 2 Barron’s book at the same time like hand in hand?
I’m taking the test this June and December but I still want a high score on the June test even though I have enough time to study for the December test.
Tips and advice please since I have 2 of the latest Barron’s WH books.

@klocheckmaflo I would use the 2015 Barron’s along with the College Board’s book and online questions.

These recommendations are based upon my experience studying for the June 3rd test on Math level 2 and U.S. History.

NOTE: The College Board reuses some practice questions and tests throughout their books and online problems.
