Startup Idea : College Notes: The Best Way to Take Notes

My idea is very simple. I went to college and it can be very overwhelming. Especially if you're shy. If you miss a class or don't understand an assignment it can really put you behind in a class. My Idea: A place where you can share class notes and ideas with other students in the class. - Select your college, class and professor that teaches the class - Link up with other students who are also in that class. - The syllabus could be uploaded along with any notes from the lecture. - Questions could be submitted with hopes of other classmates helping others. - Study groups could be formed as well There are a lot more ideas that can stem from this. What are your thoughts? I have no developer experience for this idea. Any help would be amazing!
