at a jc, I feel it is alot easier because its:
1. usually a semester system vs. quarter system (in california)
2. not curved
3. professors have a more hands on approach in teaching
4. test you more often (so you're grades don't depend on a midterm and final).
5. your class size is way smaller 50 vs 400.
Cons of a JC system:
1. funding, some cc/jc schools lack funding, and lack classes
2. Your class may range from incompetent to competent (i.e your classmates).
3. it tends to feel like the 13th grade.
4. location, campuses located near big 4 year institutions, usually have better instructors (i.e. moonlighting professors from the big 4 year campuses, and in that case, you are getting a very good return for your money), and other campuses do not.
In terms of transfering to pharmacy school from a JC, I found those that have the grades, have the ambition, and motivation, they would have transfered regardless of the institution they were attending. At the JC I was attending there were 4 of us who made it into pharmacy, 2 got into dentistry ( post-bac classes), and 1 vet. school ( post-bac classes). All of us, were on the top of the food chain. It would have been no different if we went to a 4 year institution.
However, I am not saying people should choose a JC over a 4 year institution. A JC should be the last resort, because it really is for people who don't have any other chance of getting a higher education, or are there to tie up some loose ends before moving on to graduate school. This means, you don't have room for error (if you screw up at a 4 year, you can just change majors, or take classes at a JC. If you screw up at a JC, you may not even make it to a 4 year institution, let alone a pharmd program).
