i think this should be no problem...
i'd think of some table layout like this:
date int PRIMARY
student_id int PRIMARY
then you should get about 360,000 records per year.
i saw people on this list reporting about millions of records etc... and i guess they had
a little greater tables than you should get here.
but why would you want to move any previous records to another table all the time? just
keep it in one table and back up anything older than 5 years or so. that keeps your table
at, say 50 MB, and you can run real-time queries anytime :)
