Please note:  All students are required to complete a web-based placement assessment called ALEKS to determine readiness for entry-level mathematics and statistics courses.  Entry-level mathematics and statistics courses that require the ALEKS assessment include MATH 023, MATH 120, MATH 124, MATH 125, MATH 127, MATH 131, MATH 171, MATH 181, and STAT 150. More information on ALEKS and a link to the assessment can be found at http://www.unco.edu/nhs/mathsci/undergrad/placement/placement.html.
