I just finished the PostBac at LECOM and will be moving on to finish the MS in Biomedical Sciences this year.
Ok, the PCSP.
Nobody 'starts out' in the PCSP. At LECOM Erie, you have 3 different pathways: LDP, PBL, and ISP. The reason I say at Erie is that Bradenton and Seton Hill are PBL only. The way the PSCP works is that you apply for the program but you MUST start out (fall semester) in LDP. If you seem to be making it...good grades, etc...you then can apply to the PCSP. The PCSP then starts winter semester at which point you break away from the rest of the LDP group. Last year ended up with 11 of the 12 slots filled.
The PCSP can be a good option for some people...but can also be dicey if it's not absolutely where you want to end up. The reason I say 'dicey' is you will absolutely be handicapped when it comes to picking a residency...and yes, you're going to be stuck doing primary care.
Anyone seriously contemplating the PCSP would be well served to speak with a number of different physicians regarding the program before making a decision to attend it.
A simple reality when picking, interviewing, and matching at a residency is that you have to consider the following...something that isn't ALWAYS the case...but is generally true. Most, if not all, programs directors are: Republicans, very conservative, and view any 'pathway' other than normal 'lecture discussion' to be fairly sketchy. They most certainly look at PBL students with a large amount of skepticism...and will, without a doubt, look at PCSP students likely with some form of disdain.
The PCSP is a good option for some people, but know what you're getting.
Good luck.
