I was sitting in a lecture theatre as an adult with around 250 other (much younger adult) students in a first year university (college)biololgy course.
The grading system for the courses at this university was:
7 - High Distinction
6 - Distinction
5 - Credit
4 - Pass
3 - Conceded Pass
2,1 - Failing grades
The lecturer said, "There is no one so deserving of a grade of 1 or 2 as someone who doesn't ask questions."
Now a teacher does appreciate that someone has made some effort to discover the answer for themselves. That shows the teacher that the student is serious and they are developing their own skills as an independent learner. But when you cannot get the answer or it is taking way too long (or maybe your question is "Point me in the right direction so that I know how and where to start.") - go to someone who can help and ask.
