How should I study for the biology CLEP?

[DIGI-212]

Hey there!
I'm planning to take the Biology CLEP this summer.
I so far finished watching the videos ModernStates provides on the Biology CLEP. But I was thinking about buying a subscription to study . com but are there any other resources that I should use? 

Is InstantCert is enough study material alongside ModernStates videos?
Do I really need to buy study . com?

Thank you!

I have not used Modern States but I have used the Study.com Biology Clep Prep. Take the practice test (don't guess, only answer what you are sure you know) then watch the videos for everything you miss: https://study.com/academy/course/clep-bi....html#exam I think you can access this with the $35 membership for 1 month.

I also used REA and Peterson Practice tests. Both are much, much harder than the CLEP. 

Quizlet and Cram.com both have Clep flashcards that are pretty spot on for what you will see on the exam.
