Hey Rose,
The first year certificate program is comprised of 29 credits (some courses are worth 7 credits due to labs). PCOM also runs on terms - Fall, Winter, and Spring. This means you're taking approximately 10 credits per term. Grad school is different from undergrad. It's not so much the credit load as it is the difficulty of the courses. The second year credits depend on which track you choose to take. (I presume they're about the same - I'm graduating with 50 altogether)
There are 3 Master's options for your second year: 1) Organization, Development & Leadership (ODL), 2) Forensics, and 3) Research.
1) The ODL track is more of a business approach to the structure and functions of organizations. Your classes range from the business of organizations, to team dynamics, to personal and professional development. Your classes are much smaller too (~12 students). This is a popular program for working adults looking to pursue their Master's in ODL. Hence, the students range from ages of 22 - 55. This is the option I chose to pursue and I'm graduating this summer with my Master's in Biomedical Science, with a concentration in ODL. I really enjoyed the program and highly recommend it to individuals that want to learn more about leadership and organizations. (Think owning a private practice someday)
2) The second option, Forensics, unfortunately I don't have much info about. I do know that to get a Master's from that program, you have to put in 2 additional years (3 altogether). It also involves some sort of Spring Internship (unpaid).
3) Research is research. You team up with a group of professors at PCOM who are already performing studies on certain topics. You pick one you like, do a proposal, write a thesis, etc. You have the chance here to be published. Like ODL, this should only be 1 additional year.
To get into any one of these 3 programs, you must maintain a 3.0 GPA your first year as a certificate student. At some point during your Spring term your first year, you apply to one of these 3 tracks. No new LOR's should be needed, it's a pretty seamless matriculation. The classes first year are very difficult, but it is possible to get all A's. Class usually runs 3 nights a week for 4 hours each night. I had a part-time job as a daytime waitress for 12 hours a week. The rest of the time, I spent studying or in anatomy lab. I had a life too, don't worry. But this program is meant to boost your GPA for medical school, so you really want to give it your all. (By the way, I did not receive all A's or anything - don't fret if you do poorly on one exam)
Hope this helps!
