How do I know how much I'll make in tuition from a certain class?

 

At the top of the page, click the Income Estimate button.

 

The system then displays each student in the class, their total tuition, and the amount that they pay in tuition for the selected class.  This would take into account fixed fees, discounts you set up, different tuition rates, etc.  The Income Estimate also adds up the amounts for each student and shows the total for the class at the bottom.
