Is it bad to drop an AP class?

I asked to be on the 2015-2016 roster for AP Computer Science A last school year. However as soon as I started, I began having problems with the class. During the 2nd month I couldn’t understand the materials. I’m almost failing this class and it’s the second semester already. I want to drop the class, but my school has a policy that I need to go through the Administration to be put off the roster. Should I drop it? If I drop this class my GPA can actually go up a lot. It’s my only grade that is below my standards.

Drop it asap.

Does it look bad for College Admissions? Also yes I will drop it as soon as I arrive to school on Monday.

Looks better than almost failing

Agreed.
