Scripps is not a good program anymore. No one can seem to verify or give actual data for the statistics reported on their website, and I suspect matriculation it is much lower than advertised. They do not tell you that 3-4 students, on average, drop out of the program per year (out of 13-15 total students), basically 25% of the students who started either drop out or become part-time. While the program was supposedly good when Jodi Olsen was the director, the advising now is non-existent and not helpful.
You are basically on your own as far as volunteering/shadowing set-ups, you have to take the same route as everyone else to volunteer at a hospital in the area (Scripps has no "in" with local hospitals or doctors, or they only have a very basic connections that aren't beneficial) and it can take well into the fall semester to set something up. There are also practically zero research opportunities since you are part of a college - it is not a large university with the resources you would expect from one.
The teaching is very, very mediocre - the small class size actually doesn't mean anything because the teachers still use Powerpoints and lecture format - it wouldn't matter if there were 30 or 100 students. You are not able to pick your own classes or teachers as a post-bacc, so you better hope you get placed with a good teacher (which is rare). Post-baccs are also separated during the year - you will only be with one or two other post-baccs in your classes, thus the workload for each post-bacc varies considerably. You are in the same program, yet are graded by very different standards depending on what classes/teachers/labs you get. Most of your time will be spent doing tedious, meaningless tasks geared towards freshman.
Since Claremont is a small town, and there is not a large graduate program, it is extremely difficult to find high quality tutoring. There are very few good resources that provide academic support - you are mostly on your own.
Although Scripps might be right for some people, I would strongly consider looking at all your other options. Knowing what I now know, my choice would have been very different.
