College Composition Exam vs AP English Literature Exam

I was wondering if it would be more difficult to get a 50 on the College Composition CLEP exam or a 4 of the AP Literature and composition AP Exam.

I am wondering because I am trying to get my AA before even graduating from high school and the only requirement that I might not meet is getting a 4 on the AP Literature exam because I need it to get the credit for ENC 1102. I received a 3 on AP Lang, so that gives me the credit for ENC 1101. In the case that I do not get a 4 on AP Lit exam, neither do I get a 50 on College Composition exam, I still have the chance to take ENC 1102 over summer, but would prefer not to.

Again, I am a math nerd, and I got a 3 in AP Lang. So if you think that getting a 50 in the College Composition Exam or a 4 on AP Lit exam is impossible for me, please let me know, I can handle it haha

And if you have any reccomended study tools for the CLEP exam, that would be much appreciated as well.

Thank you
