I know it's frustrating but whoever is proofing your papers is just doing their job. Just grin and bear it one more time. I was just telling my supervisor this morning pretty much the same thing. Those letters you get are evidence of someone elses work. They have to find something in order to justify their own job every time you submit.
Speaking of english 101 I didn't like that course either. You should see the one I am in now though. I'm required to learn to use the computer and internet. The first class was 4 hours of learning what the mouse is.
