Math Resource Room (MRR) Policies

The Math Resource Room (MRR) is located in WTHR 313

**The Math Resource Rooms is closed for Purdue University Holidays and Breaks, the week of Thanksgiving, and during Finals Week**

The MRRs are staffed primarily by teaching assistants for these courses.

The common office hour schedule is available here:

How to Use the MRRs:

  • To study: Use the roundtables in the MRR, or space in the Math Library (third floor of MATH) or the computer lab (MATH B101).
  • To ask a question: Stand in line in the MRR and wait to be called.

Additional resources:


  • DO attend class to learn the material. The MRR is not a replacement for attending class.
  • DO ask specific questions (e.g. “I know I need to take the derivative, but am having difficulty with the quotient rule”).
  • DO collaborate with other students.
  • Do NOT ask an instructor to sign a form.
  • Do NOT charge electronics (this is a safety hazard).
  • Do NOT ask an instructor to do your homework for you.
  • Do NOT ask for help for a class not supported by the MRR. The MRR supports MA 15300, MA 15800, MA 16010, MA 16020, MA 16100, MA 16200, MA 16500, MA 16600, and MA 26100.
  • You may be asked to leave if you do not follow the policies of the MRR.
