Math 122B requires enrollment of Math 122A in the same semester (or a previously recorded grade of C or better in 122A).  Try adding Math 122A first before adding Math 122B.

Math 122A prerequisites are either:

• Sufficient Math Placement score (U of A ALEKS PPL score of 75-100%)      OR
• Completion of Math 120R (Pre-Calculus) with a grade of C or better

Transfer credit for the prerequisite courses may suffice.  Please review the transfer credit information at http://math.arizona.edu/academics/placement/credits
