Will I be ready for my clep exam?

[JMatt502]

Hello,

About two months ago I passed my first clep exam, Intro to Psych. I prepared way more than I think I needed to and crushed the test. 

Following this, I took a break to worry about finals and put my focus on other studying. 

I then had this great idea that I could pass the A&I Lit clep with no studying. I'm an awful reader. Failed with a 46. 

Since then, I have purchased an Instacert subscription and have thoroughly ran through about 3/4ths of the flash cards. I then got antsy on practice tests and took the three Petersons tests with scores of 60, 54, and lastly a 59. I also found some other practice test, not sure whose it was, but I think it may be an older versionof the official study guide test. Scored a 51/88. I was wondering what your alls opinion is if I were to finish studying the flash cards, review the Petersons questions I do not know the answers to, and and look through the specific feedback forum to ensure I know all concepts mentioned. 

Should I then be prepared to pass the exam ?

I'm not looking to spend money and time to receive another failing score.

Thank you!
