Attitude towards coach

Recently, me and my coach have been arguing a lot and it's becoming a detriment to me going into the clubs top squad.

I don't know if it's my recent mock exams or something else, but most of the time when I get a bad erg score or the coach says something I get frustrated about, I get angry and potentially argue with them.

This doesn't help considering my own coach has a short temper, and yells frequently when he feels someone is being disrespectful (e.g giving a bit of complaint about crews).

I have talked with him about this and all he says is "stay quiet and just say yes and thank you to my choices and advice" and while I've been trying to do that every session it seems to be the same scenario.

Any tips?
