Attention, future medical professionals!

We are happy to announce that Khan Academy will retain our MCAT course until 2026 with the support of the Association of American Medical Colleges (AAMC). We continue to work to improve the MCAT course to make it the very best it can be. Towards this end, we have updated over 80 Biological and Biochemical Foundations of Living Systems (BBLS) passages in Unit 2 of the course. Please click here to learn about the passage improvements and how best to use these passages to prepare for the MCAT. We wish you the best of luck with your studies!
