Webwork Fee ($75)

Webwork Fee Due Date: Tuesday 09/26/2017 at 10:00am.

Webwork can be used without paying the fee until the Webwork Fee Due Date.

If you pay the Webwork fee and later you drop the class, the fee is not refundable.

If you are yet not sure whether you stay or drop the class, use Webwork till close to the Webwork Fee Due Date without paying the fee.

Pay the Webwork fee when you are sure you stay in the class. Try to make this decision by the Webwork Fee Due Date, to minimize the risk that unforeseen circumstances could force you to past the Webwork Fee Due Date and being dropped from Webwork.
