@MariaZulch -
If you have access to all of the courses you want to pull the information from, then it can be done with API's (I think, I'm not an expert or even a novice but I have seen enough about API's that given the correct criteria, I believe you can pull that information).
If you are not the teacher in all of the courses, then an administrator would have to do it. I would contact the admin at your school and ask if they know how to use API's to pull information. you would need the course id for each of the courses and the canvas student id.
I may be off base, but I figured I would put the information out there. This question is probably better suited for the Canvas Data Users or Canvas Developers group message board.
