I think I just failed my AP exam?

I'm a sophomore and I took my first AP class this year, AP European History. I maintained an A for the whole year. I started studying for the exam April 6th, and I actually studied. In May I studied for at least 4 hours each day and last weekend I didn't leave the house at all and studied the whole weekend. I thought I was going to do very well on the exam, but I just took it and I'll be lucky if I get a 3.

For the multiple choice, I thought it was very hard and randomly bubbled in 73-80 because I ran out of the time.

For the essays, I took too long on the DBQ (I'm not good at DBQs in the first place) and the proctor announced we should begin working on the essays now and I was on the 3rd paragraph of my DBQ. So I abandoned the DBQ and went to the essays.

The prompt I chose involved stating the differences of the impacts that some intellectuals had on Europe and I ended up writing an essay about their similarities... I noticed what I had done when I was finished with the essay. I crossed out the essay and there was 45 minutes left.

I wrote the 2 essays (they were horrible, a thesis with 1 body paragraph containing 3 sentences) and went back to finish the DBQ. I finished the DBQ but it was rushed and wasn't very good at all.

Should I go take the CLEP? What will getting a low score on this exam do to me?
