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 has precise prerequisites that must be met:


  • Sufficient Math Placement score (UA ALEKS PPL score of 75-100% or Prep for Calculus 70-100%)      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
