You think -that's- there's no point of being very very picky about pronunciation,
You're on the wrong class.
You...probably You'll have to try something else.

I'm transcribing the teacher's class recording to learn English.
Could you correct what I misheard, missed, or punctuated incorrectly?

"You think that it's...there's no point in being very, very picky about pronunciation, you're (in/on) the wrong class. You probably will have to try something else."

She's right: pronunciation is very important. She is speaking very quickly here though, and it makes her words unclear to me in two spots.

The first: "on" vs. "in". Grammatically "in the wrong class" makes more sense to me. I think she probably wanted to say "on the wrong track" at the same time, and the phrased got mixed up.

The second: "you'll" vs. "will". I definitely hear "will have to", but the first part of the word is not fully pronounced.
