Export them or print them? (Or save as PDF and email them?)
You can make each note a different record. Then exporting/printing/saving as PDF are all a matter of pulling up the desired records in a found set first before doing the print, export, or save as PDF operation.
You would use one table to list each student and a related table to list each 'quick note' so that you can link multiple notes to the same student. A portal on the student layout can be an easy way to create and fill out new notes on that student.
