How do you make up work?

I have Co-op Chemistry and Brit Lit classes twice a week.  The kids miss class and get behind.  Shocking.  I do a lot of make-up, catch-up, or tutoring once a week, on Thursdays.  Now, Anna is taking Human Biology during Thursday mornings.  I get her started and then work with two or three other kids.  Today, Anna and Andrew worked through some Stat exercises on the graphing calculator: linear regressions, variance, r coefficient, and residuals.  Anna missed the graphing lesson before class on Tuesday.  Andrew is going out of town for a week; he needed to review the graphing.  (I do the graphing exercises on the TI 83/84 with my husband’s kids.  He can’t get the knack for using the graphing calculators.). Andrew #2 needed help with metric conversions.  I had given four worksheets as homework and he had many mistakes.  It turns out he was entering data incorrectly in his calculator.  (Here is how to enter numbers in scientific notation.). He got a free lesson in nomenclature with Gen, who’s out all next week, too.  I gave Gen some notes, practice, and a quiz.  In between, I worked with Anna, who has the patience of Job.  If you have a Co-op class, carve out extra time for individual help.  Tomorrow, Andrew is taking a metric quiz before class and Joe is staying after for help.  Joe and Lacie need to do a lab; I’ll have them complete it right after Chemistry class while I teach Brit Lit.
