The person above is incorrect. In a semester or quarter (whichever system the university uses) you can take up to a certain number of credits and each class is worth a number of credits. For example, at my university we are advised to take no more than 18 credits per quarter and classes usually range from 1-6 credits.
In your situation, classes would probably be similar credit-wise and you would pay $955 for each credit. If a class is 3 credits, it would be $2865.
