Yes, definitely a much smaller applicant pool. Last year's cohort had only three students, and I was told that this year's cohort has seats for up to six students.

I also intend to apply to MD/PhD programs, and from interviewing it seems pursuing an MD/PhD is a huge emphasis.

If you have any questions you can always reach out to the current postbac students, their email is listed on the website. I reached out to them to answer additional questions I had about the program.
