Answer 1

I don't know how to code this but if you put check boxes
[] Jonathan​
[] Bob
[] Jerry

then test for each checkbox to be checked, if it is checked set a variable of 1, if it isn't checked, set it to 0.
then make a GUI and have it display names, present/absent, and excused or unexcused absence!
but make it so you can update if they were late!

Answer 2

1 is present
0 is absent
