The creation of a macro is required

We need a macros specialist. A macro is required to schedule the training center. We need a macro that helps us to set up a schedule in a small training center.
Issues to be addressed:
1) The actual schedule (there are morning afternoon and evening groups, but it is impossible for the same classes to be held on the same day in different groups).
(2) tracking of the recruitment of listeners in groups
(3) The calculation of the employment of teachers, for the calculation of remuneration.
(4) audience distribution.
