Not trying to troll here... but this logic is terrible.... the number of schools is based on the need for the professions. Think of how many pharmacists are out there vs opto and pod.... Every major grocery store, hostpital, walmart, all have many pharmacists working for them on top of the hundreds of independent dealers. Think of it this way pharmacists are filling prescriptions for every type of doctor in all of medicine...
If you want to know truly how competitive it is, i might suggest midwestern.edu.... they have a med, dent, pharm, pod, opto, and a variety of other professional schools. Look at the average GPA and the number of applicants... that would give you a fair example of how competitive each program is. I know for example that the opto program at midwestern had about 500 applicants vs the 2800 applicants for the dent program. Now this is only one school, however it is one of the few universities that has alot of prof programs and i feel it is a good representation of all. I researched and shadowed many professions before deciding on dentistry.
Bottom line... asses you abilities and interests then go from there.
Good luck!!!
