Is it alright to thank my Master's thesis advisor, via e-mail, for getting a good grade? So, I received the grade for my Master's thesis over the weekend. I defended my thesis late September, and received my grade yesterday (due to university rules). I waited about 4 months to receive my grade, and it was well worth the wait. 

So I was wondering if it's alright to shoot my professor and advisor a thank you e-mail? I am very happy with my grade, but I was wondering if it's a weird/improper thing to do to thank a professor for a grade they've given. Does anyone have any experience with this? I would greatly appreciate it, thank you.
Instead of thanking her for your grade, I would thank her for the time and energy they spent with you during your thesis, as well as what she has taught you. You earned your grade, she did not hand it to you.
