UCLA Extension currently does not offer an MCAT preparation course or review session(s).
UCLA Extension and UCSC Extension have collaborated to offer an MCAT prep course: https://www.ucsc-extension.edu/Premed-Postbaccalaureate-Program/mcat-prep-course/
We also advise students to look into various test-prep centers that offer MCAT preparation courses. Furthermore, you can gather some very helpful information at the Association of American Medical College website. Here, you will be able to access practice exams.
