I am planning to apply for Ph.D programs in mathematics in U.S. and I am thinking about which professors I should ask for letters of recommendations from. In order to get "strong" letters, I need to determine which professors believe I am really strong.
Although I do well in most of my classes (I am always trying to get full marks on my homework and tests), I do have a "bad" habit of asking stupid questions frequently. I can see from the faces of professors that they dislike students who always ask stupid questions, while welcoming students to ask questions. (If you are a professor and don't think this is the case, please let me know...I really appreciate it.) I feel like professors prefer the questions that will make them have a better understanding about the subject instead of the questions that they will waste their time on.
What do professors think of a student who has good grades but always asks stupid questions? Should I expect good letters from them? Or I should go to the professors whom I seldom ask questions (but still do well in their classes)?
Well it depends on your ability on the assignments to an extent. There are people who get As because they memorize proofs and methods- a diligent track to an A. Then there are people who author their own work and really have a command of the material, coming up with their own ideas.
