Is there any way to filter questions by a certain number of subjects (e.g., real analysis and differential equations)? Additionally, is there a way to filter the questions by difficulty?
The latter question, I feel, is more important. I'd like to participate more in Mathematics SE by answering more questions, but far too often I encounter questions in areas I haven't studied or are at a much more advanced level, making the entire process of questions somewhat difficult.
I propose that questions could be labelled as "high school", "undergraduate", or "graduate". (This would not be the same as a tag, however, since tags aren't always comprehensive by nature.) Filtering questions this way would allow people to find questions that are more suitable to their level of understanding, and potentially mean more questions could be answered. So, for example, if I were to post a question, I would tag it with differential equations, and click one of three boxes labelled as "high school", "undergraduate", or "graduate".
I'm not suggesting this is the only solution; my intention is just to find a way to contribute more. From my experience, most people who answer questions are professors or Ph.D candidates.
What do you guys think?
