InstantCert for US History 1

[zapproximator]

Hey Silly_Me,
So Instantcert does divide everything up into sections, and for history, chronologically. For example, in CLEP US History 1, it's broken up like this:
Colonial Period to the American Revolution (1500-1787)
The Newly Formed United States (1787-1824)
Jacksonian Democracy and the Mexican War (1824-1850)
Sectional Tensions and the Civil War (1850-1877)
Philosophy and Politics of the Time Period

Here's my solution for dividing the early explorers flashcards up. Just mark the early explorers and study those marked cards as your own custom sort of deck (if you want it to, for however long you want, it will just show the marked cards).

So it doesn't have a section for JUST early explorers, but instead it has sections for the major time periods covered by the test.
BTW, I'd really recommend you try Instantcert. It's awesome. And if you change your mind, you can get your money back no matter what within 30 days.

Hope this helps you make a decision!
