hey, im not quite sure if i understood what you were asking, but i may have.

you could simply name the check boxes whatever the students names are.

so inside the tag that creates the box, say name = <?= echo $studentname ?>
then when the form is processed, it will know which box applies to which student.

or something along those lines. hope this helps.

I'm guessing you have a "key" for each student record in the database?

In your while loop you could do this

while ($array=mysql_fetch_array($qry)) {
etc etc
<input type=checkbox name=students[ ] value="<? echo $array["key"];?>">
Student Name
}

Then the form send an array called students, run a foreach on them and do as you please with them.
