Now I'm confused.
I thought what you wanted to do was something like an attendance register, where the attendance or absence of each student would be recorded each time the class is in session.
(This isn't done by individual student, but the attendance of the whole class is done every session, in one insert).
You would link this attendance table to the student table so you could see which students were present/absent on any given day
Are you saying that you want to look at each student individually and insert their attendance/absence that way? that seems like more work to me
