Keystone Tutoring Program

Tutoring is available during the fall and spring semesters for CHEM135, MATH140, MATH141, MATH241, and MATH246. For Spring 2022, tutoring will be held in person beginning January 30th.

In order to ensure a tutor will be available to assist you in the course you need help in, be sure to check the course syllabi. To receive the best support possible, please have your course textbook with you. You can also receive support in your Physics classes throughout the semester at the Slawsky Clinic and in your math classes through the Department of Mathematics Undergraduate Tutoring program or the Math Success Program.

Spring 2022 Tutoring

Tutoring will be held in person for Spring 2022, beginning January 30th (unless campus policy changes). If requested by a student, and if the tutor is comfortable doing so, tutoring can also be arranged through video conferencing via Zoom

In tutor video conferencing, students and tutors should do the following:
  • Dress and act appropriately during the meeting.
  • Use your full name (first and family names) on the screen. 
  • Remove any inappropriate or potentially offensive artwork, pictures, etc., from your background.
  • Please attempt to maintain privacy during these meeting times through the use of headphones or private rooms. In other words, try not to be in a location where your conversation can be heard by others or that is distracting to the others or tutor.
  • Allow a reasonable amount of time for the tutor to answer your emails. If they do not answer within 24 hours, please contact keystone@umd.edu
  • If at any time you feel uncomfortable with the person or the conversation during a virtual meeting, inform the them you are discontinuing the session then shut off the video. Inform Dr. Nicole Roop (nroop@umd.edu) immediately of these situations.
