<p>Hi,
I just want to thank my professor for working hard , dedicating and caring about students. I dont think i did really well on exam. Do you think writing to him before the grades are out will sounds like i am trying to be nice and get a good grade......... ( I am a graduate student)</p>
<p>I think it would be best to wait until after your final grade for the class is posted.</p>
<p>Wait until after the grades are posted.</p>
<p>I would concur with the others. Wait until after grades are posted.</p>
<p>I think you can send this email whenever you want. I am a TA managing grades, and a few students said things like this to me on the last day of class and sent emails like this to me. It didn’t affect their grade, and I didn’t think any less highly of them either.</p>
