Tutors in Chemistry

Teaching Assistant Tim Shelton, a graduate student in chemistry, goes over students' questions outside the Chemistry Annex on Tuesday, March 18, 2014.

The tutors listed below, in no particular order, are graduate students or postdocs in the Department of Chemistry. All tutoring arrangements are strictly between you and your tutor. The Department takes no responsibility for the quality of the tutoring experience.

Peer tutoring is also available at no charge for select upper division courses.

NOTE: A graduate student may not tutor any student in a course which they are also a TA for in the immediate quarter. Should this occur, both individuals will be promptly referred to Student Judicial Affairs. For example, if you need tutoring for CHE 2A, you may not be tutored by any graduate student who is currently a TA for any instructor of CHE 2A.
