I happened upon this quiz which I thought might be helpful to the differential calculus student.
It is multiple choice so if you get stuck on a problem you can just guess. And in case you had to guess you are shown the solution for finding the answer so that you can learn about calculus as you go rather than simply skipping to the next question.
Furthermore, the questions seem to be in a random order which makes the practice quiz ideal for doing again and again.
Also, if you are going to take that exam you may want to make reference to a table of differentiation rules such as this one:

How are you today? Thanks for the site!
In mathematics, you don't understand things. You just get used to them.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
