What Class Should You Take?

Note: Be sure to first check with your major advisor(s) to determine your first mathematics course.

One way to determine which course you are qualified to take is by ACT Math, SAT Math, or COMPASS Math scores. See the chart below to determine which course you are eligible to take.

ACT Math or SAT Math or COMPASS Math You can take
0 – 18 or 200 - 460 or Algebra 0-35 Math 108, 123*
19 – 21 or 470 - 510 or Algebra 36-60
College Algebra 0-44
Math 108, 123 *, 130*
22 – 26 or 520 - 600 or Algebra 61-99
College Algebra 45-48
Math 108, 123*, 130*, 143, 144
27 – 28 or 610 - 640 or College Algebra 49-50 Math 108, 123*, 130*, 143, 144, 160*
29 – 36 or 650 - 800 or College Algebra 51-99
Trigonometry 51-99
Math 108, 123*, 130*, 143, 144, 160*, 170, 176*

*Warning: Do not automatically enroll in the highest math course available based on your exam scores. Many courses (including Math 123, Math 130, Math 160, and Math 176) are terminal courses and do not provide the prerequisite preparation needed for other required courses. Check with your advisor and/or the Mathematics Department to determine which course is best for you.

Pre-Requisite Requirements

In order to support and improve the success of our students, the Mathematics Department follows the pre-requisite requirements as described in the course catalog, without exception.

  • Overrides are provided only to those students who have satisfied the pre-requisites either by having completed the pre-requisite course or having sufficient exam scores. If a student has documentation showing updated exam scores or unofficial transcripts they should come to the Mathematics Department office (located in Brink Hall, Room 300) or submit transcript or scores by email/fax for an override.
    The Mathematics Department must see the updated scores to provide the override.
    • Please send override requests to with official scores or transcripts included.
  • If students would like to challenge their math placement they can take the COMPASS Math test.
  • If a student believes he or she would test into a course higher than Math 170 they will need to contact the Mathematics Department to be evaluated. To place into a course above Math 170, a student will need to have proof of successful completion of pre-requisite courses on an official or unofficial transcript.

COMPASS Math test

  • Students not satisfied with their ACT or SAT placement are strongly encouraged to challenge their placement by scoring high enough on the computerized COMPASS Math test.
  • To take the COMPASS Math test at UI, go to the UI Counseling and Testing Center, located in Mary Forney Hall Room 306. Their phone number is (208) 885-6716.
  • The COMPASS exam is also given at all universities and colleges in Idaho, and at many throughout the United States. If you take the COMPASS exam somewhere other than UI, ask them to forward your results to the UI Admissions Office and to the Mathematics Department.


If you have any questions, please contact the Mathematics Department at (208) 885-6742.
