toxin--sorry about those Sooners!
About the Tulane Cell and Molecular Master's--basically, the program is designed for pre-profs to get that "bump" they need to get into their school of choice. With that in mind, the curriculum is planned to fill in any gaps you have from undergrad with graduate courses--like if you haven't had a physiol course, you'll take that. Most of the courses are mixed grad and undergrad, so grad students do something extra, like research papers and book reviews, or have different tests. The workload will definitely keep you busy, but it's very doable. The department is heavy on developmental bio and neuroscience, so there's lots of advanced courses (ie--devlopmental neurobiology, neurobiology of disease, molecular biology of cancer) in those areas along with physio, cell, molec, biochem, etc. I'm working full-time in research and doing the program part-time, and my grades were fine.
The program directors are awesome--so supportive and very laid-back, they really want you to succeed. They do interview coaching, LORs, whatever you need. I think you can apply through mid-summer, and it's based on grades and MCAT scores; I don't think it's highly competitive, but it's a really good group this year.
I think the best aspect of the program is the patient skills course--you shadow in a hospital, go on rounds, take histories, psycho-social interviews, etc., and then discuss it twice a week in class. It focuses on developing good bedside manner, and really delving into the patient side of medicine--what really makes you a good doctor. You switch departments for each semester, so fall you may be in oncology and spring labor and delivery.
Success rates--the program seems to have a pretty good success rate. I don't know numbers from previous years, but this year several people have acceptance offers already and lots of interviews (I'm not applying on this cycle).
I'm very happy with the program and I'd recommend it to anyone. Hope this helps!
