This test is 90% on calculus or precalculus. I did not do well but my friends who spend one month reviewing Stewart got perfect mark rather easily. So try to work on as many dumb problems as possible in Stewart's book, it will help.
In case you decided to go to graduate school, it will help you in TA sesions as well. Before the test, the undergraduate students will ask you three question in a minute and you have to sketch a proof for any problem to them in 20 seconds. In my case the department advisor just sent me to the math helproom and claimed I can help any student in any subject whatsoever, and that is my experience of life as a teaching assistant.
