This is a Flash program file containing 54 practice questions on closed curves.
The questions appear when the program is run, and the pictures of the graphs can be enlarged by simply clicking on them.
After doing the questions, they can be submitted and then reviewed, to see if they have been done correctly. Whether you have done only one question, or all twenty, the review option is still available.
Please see screenshots of the program or download the sample (which includes 5 questions) to get a better idea of what I mean.
I have often give questions + exercises in this format, as it can sometimes help students with learning barriers (writing difficulties, for example) and students tend to interact more with, and become more receptive to, technology in the classroom.
If you would like a printed copy of the same questions, please check out my other listing:

Thanks for looking and I hope this is a use to you.
