I'm a little confused by your question. I'm going to assume you mean: how does tution work for the 2+4 path?
Well, the two years would be pre-reqs and you would pay the tuition of whatever institution you are attending, whether CC or 4-yr school (note that some pharm schools attach a stigma to pre-reqs from CC). From this point, you would apply to the professional portion of a 0-6 pharm program, at which point you would pay their tuition rates.
If you don't want to get a Bachelor's Degree, then you might as well try for a 0-6 program because you might not get your spot after your 2 yrs of pre-reqs.
Also, if you're looking for more flexibility (in case you end up wanting to get out of pharm), then getting a 4yr undergrad then doing a 4yr program isn't an awful route. I'm looking at doing a 4 yr undergrad and then a 3yr accelerated pharmD program.
Best of luck!
