After applying, transfer students are required to update their grades and course records.
You must provide your final grades from the previous term and list all courses in progress or planned for the term before you expect to enroll. Your updates will ensure UC campuses have the most current academic information available. Even if you do not have any in-progress or planned courses and your record of course grades was complete in your original application, you must log in to your application and complete the Transfer Academic Update.

TAUs need to include grades through fall 2022 and planned coursework through summer 2023. The priority deadline is January 31, 2023.
