Make sure to include "AATC 118B" in the Subject line.
Please email me directly to gain access to videos and annotated notes on Canvas.
Starts Thursday, June 26
Monday through Thursday various times:
Please contact me in advance at enlamsen@ucdavis.edu to share what you would like to cover, especially if you have a lot of questions!
Please sign in (CHE 118B Workshop/Chemistry Office Hours/Appointments) each time we meet. You must have a Zoom account under @ucdavis.edu address to join.
Signing in whenever you attend workshops, office hours, and appointments helps us at the AATC to continue to provide the services we offer our students every quarter. Thank you in advance!
If you come across any websites or videos that you find helpful and would like to share these resources with other students, you are welcome to email me with those links. I will post them on the bottom of this page. Thank you!

About Academic Assistance and Tutoring Centers (AATC)
About Academic Assistance and Tutoring Centers (AATC)
Academic Assistance and Tutoring Centers (AATC) exist to help undergraduate students thrive at UC Davis and beyond. We provide an inclusive and interactive environment where students participate in reinforcing and retaining knowledge in multi-disciplinary writing, math, and science+ through co-curricular academic services provided by both professional staff and peer tutors. We strive to support students in developing the academic competence and confidence that will empower them to succeed at UC Davis.
We offer workshops, tutoring, and/or content reviews - free of charge to all registered UC Davis students. Visit https://tutoring.ucdavis.edu to view the current workshop, tutoring, and content review schedules.
More ways to get help and/or meet others from your class:
1. Drop-In: Visit one of our AATC peer tutors or Chemistry Specialists at the lower level of Shields Library. They will be there to help you with HW, exam prep, and conceptual questions from lecture. Visit https://tutoring.ucdavis.edu/chemistry for the current Drop-In tutoring schedule.
2. Remote: Book an AATC individual appointment through OASIS. (during the regular academic year).
