i did the scripps post-bacc program. and although it is a women's college, they are not allowed to discriminate the leave out applicants based on gender.
meaning... as stated above in a previous post... that the VAST majority of students there are females. there were 3 male post baccs in my class of around 15-20 (can't recall exactly).
none of the post-baccs live on campus, so it's not a problem in terms of dormatories. and scripps is a part of the claremont colleges (harvey mudd, pomona, claremont mckenna, scripps, pitzer) joint science program (mostly for cmc, scripps, pitzer students), so you end up interacting with students from multiple campuses.
it's a great program for anyone looking for a post-bacc program in CA.
