I'll answer the question about clinicals, first.
You're correct, prior to this year we had J track, 70 spots for students to rotate in different hospitals and clinics in around Atlanta metro. The rest were placed at anchor sites throughout GA, FL, and AL. This year they revamped the system, removing J track and anchor sites. Each student is now placed in regions; NE GA, Central GA, SE GA, which includes Jacksonville, SW GA, NW GA, and South Central GA. Additionally there are spots in Cahaba, AL., Atlantic City NJ, Scranton PA, and Johnstown, PA. This change has no effect on audition rotations during your 4th year. The changes are simply to improve the overall quality of rotations based on prior student feedback. There are some really solid hospitals PCOMGA students rotate at plus a few that were added this year.
As to the curriculum, you start with Anatomy, Anatomy lab and classes associated; physio, radiology, etc during first term. Second term is devoted to biochem, micro, and pharm. From 3rd term of 1st year to the end of second year, classes are systems based; Neuro, Cardio/Pulm/Renal, Endocrinology, etc etc. After first term, most of what you'd be learning is high yield board material.
Fwiw, faculty is tweaking the schedule for 2nd years in order to provide them more time to study boards. Basically, moving their schedule up so that all classes except for OMM and primary care skills end 6 weeks prior to June (or around June, not clear on the date) , which allows more time for dedicated boards study.
As to research, if you're interested, it's fairly easy to find opportunities in basic sciences research by just communicating with the faculty here. As to clinical research, several classmates were able to set that up on their own through alum networking or other means.
Teaching style: Lecture based. Classes are recorded through a program called tegrity. Labs and guest lecturers are mandatory attendance. We also have small group discussions and vignettes, but those are few and far in between.
Hope that helps.
