<human>: Give me a shortened version of the text

Hello! =)

A bit long, so sorry in adv. :P

I'm a senior in high school right now. I was hoping to take AB Calculus as it looks good to have a math senior year but my counselor was adamantly against me taking the class (she doesn't like me very much). Because I was hoping to transfer into AB Calc, I had a gap period during 3rd. I appealed to the principal, and ultimately he rejected my appeal after consulting with my counselor. I was considering re-appealing the rejection, but after talking to a friend she told me AB Calc sucked and she was trying to drop it.
 
So, now, I have decided to T.A for a teacher during my 3rd. My counselor however, called me in and told me she's assigning me to a teacher because she wants me in a class asap. I asked her if I could look at a list of teachers who needed 3rd period T.A's and she said no. I asked her if I could ask the principal to let me T.A for my old AP Stats teacher even though he already has a T.A (a lady in Administration told me a teacher could have 2 T.A's with principal approval) and she said no. She said I had to go straight to this teacher and get in her class right away. The lady seems like a nice person, but I would have really preferred to T.A for my AP Stats teacher. I have many friends in his 3rd period class, good relationship with the teacher, and I was hoping to ask him for a college rec. But now my counselor forced this teacher onto me without any say. Would it be too tactless to ask the principal to switch me to being an AP Stats T.A or should I bite the bullet and just stick with this other teacher? I would feel really, really bad switching out, and I'm not sure if it's even possible to switch, but I would have a much more enjoyable senior year as an AP Stats T.A.
<bot>: Counselor assigned me a teacher, but would have greatly preferred to T.A for someone of my choice. Should I try to switch or bite the bullet?
