Da heck why??
What's with that counselor?
I don't know. Personally, it's fairly easy to sweet-talk a teacher. Or any person in authority.
Anybody could do it. You just need to be a little more persuasive.
And bring evidence. Like, cold, hard evidence. That should do the trick to make you switch classes.
Have you tried talking to someone higher than the guidance counselor?
But yeah, don't worry about putting angst down here. This is what this thread (and subsequent friends you meet in this thread) is for.
