Do colleges hate looking at a T.A.( Teacher's Assistant) course on a transcript?

<p>I wanted to take 5 AP classes during my senior year but i couldn't because everything just doesn't match up! so i ended up with two art classes. I am going to drop one of them and be a T.A. Would it look really bad on my application. what would colleges think? I took 3 AP classes my junior year and i have 4 right now (senior year).
I've heard being a TA helps your gpa go up. how's that? do you get credits for being a TA?
i'm really confused right now. i can't get hold of my counselor right now because a lot of students want to change their classes so she's busy :(</p>

<p>so is it okay if I am a TA ? because i don't want that to hurt my chances of getting into a selective college. or is it better if i stay in both of the art classes ( i don't like one of them!)</p>

<p>Thank you for your help :)</p>
