All I'm saying is that with many schools it is very very difficult to get pre-reqs done in 2 years. For instance say they require biochem?
You have to take 1 full year of gen chem and 1 full year of o chem before you can take biochem. Unless you have AP credits, that's not very likely.
Also, while trying try to cram in all of this, you have to maintain an extremely high GPA because most schools favor, or require, a 4 year degree.
And, as said, pre-reqs will becoming even greater in a few years. 5 years from now, it will be impossible to complete everything in two years.
If you're applying to multiple schools, they will have different pre-reqs you need to complete as well which further complicates things.
Finally, no pharmacy school considers 12 credits full time. That is the classification namely for financial aid. Pharmacy schools pretty much want you to maintain, a minimum, of 15 credits a semester during your career.
