Department Policies

Registration Restrictions

Students who have successfully completed (with a grade of C- or higher) any 100-level course are not permitted to take or repeat a prerequisite of such course without explicit permission from the Chair or Assistant Chair of the Department of Mathematics and Statistics. For example, a student who earned a grade of B in Math 161 is not permitted to register for Math 100, Math 117 or Math 118.

Prerequisite Policy

A student’s lack of appropriate course prerequisites constitutes grounds for withdrawal from the class at any time.

AP Course Credit Policies

Students may receive credit for the following courses if they earn an appropriate score on an Advanced Placement Test offered by the College Board.

AP Calculus

Credit for the AP Calculus exams will be awarded as follows:

  • 4–5 on AB Calculus Exam ⇒ credit for MATH 161;
  • 4–5 on BC Calculus Exam ⇒ credit for MATH 161 and Math 162;
  • 4–5 on AB portion of BC Calculus Exam ⇒ credit for MATH 161.

AP Statistics

A score of 4 or 5 results in credit for Stat 103.

Policy on Multiple Majors or Minors

The following modifies and clarifies the "Double-Dipping" policy of the College of Arts & Sciences, as it pertains to the Department of Mathematics & Statistics.

Most combinations of majors or minors are allowed. In particular, combinations of majors will be permitted as long as students respect the College of Arts & Sciences policy that each major should include 21 credit hours not being counted for another major, along with the following restrictions specific to the Department of Mathematics & Statistics: 

  1. MATH-BS may be paired with TPAM-BS, but may not be earned together with a double-major in TPAM-BS plus any Physics major (e.g., BPHY-BS, PCSC-BS, PHYS-BS) 
  2. MATH-BS may be paired with MSCS-BS, but may not be earned together with a double-major in MCSC-BS plus any Computer Science major. 
  3. DSCI-BS may be paired with either STAS-BS or a computer science major, but not with a double major in statistics and computer science.  

All Minors offered by the department must contain at least 6 credit hours at the 200 level or above not used to satisfy requirements of any other major or minor, and at least three of these must be at the 300 level. This condition may be met by taking additional electives, if necessary, from the electives list for the minor. Furthermore, the following combinations are not allowed. All other combinations are allowed provided they meet the above criteria  

  • ACTU-MINR may not be earned together with STAS-BS or DSCI-BS  
  • BIOS-MINR may not be earned along with STAS-BS or DSCI-BS  
  • MATH-MINR may not be earned together with AMTH-BS, MATH-BS, MCSC-BS, MTED-BS, TPAM-BS  
  • OPRR-MINR may not be earned along with a double major pairing any of the math majors with either STAS-BS or DSCI-BS.  
  • STAT-MINR may not be earned together with STAS-BS. STAT-MINR may be earned with DSCI-BS but only if STAT304 and STAT305 are taken as electives.   
  • DSCI-MINR may not be earned along with DSCI-BS or a double major with STAS-BS and any computer science major.   

Otherwise, any of our minors may be awarded along with a major in Biology, Engineering, Mathematics, Physics or Statistics with a minimum of 6 unique credit hours. Other combinations where the number of unique credit hours is at least 6 but below 8 may be approved on a case-by-case basis.   

Performance Withdrawal Policy

A student may be withdrawn from any of our majors if:

(i)  The student receives 2 grades less than C- in a two-year period in courses required for the major, or

‚Äč(ii) The student has a GPA in the major < 2.0 after completion of all 100-level and 200-level requirements.

(iii) The chair has the right to reinstate students in the major for exceptional cases.

**This policy will be enforced beginning in fall 2021, meaning poor grades from AY2020-2021 and before will not be considered.
