You will need the following:
You should NOT use your own calculator. ALEKS will provide an on-screen calculator for certain problems if one is needed. This is the only tool that will be available when you take the placement exam in the proctored environment.
The choice depends on the baseline score you received. If the score is high enough to place you into your desired MAT/STA course (see placement chart), then sign-up for a proctored test via ProctorU.
If your score did not place you into the MAT/STA course you needed, then select a Prep & Learning Module to brush-up on topics to help improve your score. Recommendations on which learning module to select can be found here. Studies have shown that working 6-8 hours in a learning module can improve your score an average of 15 points - this increase in score will help improve your placement.
