What does the College Algebra test look like on the screen?

What test are you taking?

I see now from your post in another thread that it's the CLEP that you will be taking. So, to answer your question:

In the top right of the exam window while viewing a question there is an option to "Mark" a question. There is also a "Review" option that lets you see which questions you have marked and which you haven't answered yet. From there you select the question you want to go back to (by clicking on it) and then click "Go To Question" in the top right. This takes you back to that question.

The only thing I found unintuitive about the exam interface is that it took me a minute to figure out that you had to click "Go To Question" to actually go to the question (it seemed like you should've been able to double-click). Other than that, it was very easy to mark questions for review and go back to them.

Not related to the exam interface, but I personally found that the IC flashcards covered the material well. If you can answer those problems you will do well on the CLEP.
