I am in training and am working on creating course assessments (tests) for students to take at the end of class. Nothing complicated, just 15 questions with scoring in the background to give them a score.
 
I am new to this, so I am wondering about one thing in particular ... we have about 100 different courses, so we will have 100 different assessments. What is the best way to save the data from the assessments to Sharepoint? Do I need 100 individual libraries for each?

We are going to want to view the scores by course to see who passes/fails, but at some point we are going to want a big picture total report for all 100 classes. Is it possible to take the data from all these 100 different libraries and link it to a "master" library with course name, student name, date taken, and assessment score? Or, can I just have 1 library and when I need individual course information I can just filter out the class I'm looking for?

 Thanks!

I would use a normalized schema, database submit (via Web Service), and SharePoint dataviews. We have deployed similar solutions to many companies over the last 6 years. Let me know if you'd like a demo.

Thanks. I'd love any information you can give me. Like I said, I am new to this so I don't even know what you mean by normalized schema?!?
