The University of Michigan has a preferred admit program:
http://www.umich.edu/~pharmacy/prospective/admissions/preferredadmin.html
The College of Pharmacy cooperates with the U-M College of Literature, Science, and the Arts (LS&A) in a program to guarantee admission to the Pharm.D. program for highly qualified entering freshmen. Since many students feel compelled to take a narrowly structured pre-pharmacy program to enhance their qualifications for the Pharm.D. program, the preferred admission program gives already qualified students the freedom to choose more diverse courses during their pre-pharmacy study.
Students admitted to the College of LS&A will be considered for the preferred admission program in pharmacy based on their academic qualifications and their desire, expressed on their application to the College of LS&A, to enter the field of pharmacy. The College of Pharmacy Admissions Committee will select students for the program and notify them by March 1.
Students must submit their regular University admission application by the deadline specified by the Admissions Office to be considered for this program (contact the Admissions Office directly for the date). Failure to be selected for the preferred admission program does not jeopardize a student's admission to the College of LS&A or the opportunity to apply for regular admission to the Pharm.D. program at a later date.
Once admitted, students have up to three years to fulfill entry requirements. Students are considered competitive for the program if they score 29 or better on the ACT or 1280 or better on the SAT and maintain a 3.5 grade point average as calculated by the University of Michigan. They also must have completed at least three years of laboratory science (biology, chemistry, and physics) and four years of college preparatory mathematics, all with grades of B or better.
Once admitted to the preferred admission program, students must earn a grade of B or better in all prerequisite courses at the University of Michigan. They must confirm their intention to enter the Pharm.D. program by submitting a cross-campus application and required credentials by the equal consideration deadline (December 1) for the fall term when they wish to transfer to the College of Pharmacy. While enrolled in the College of LS&A, students in the preferred admission program must use the counseling and academic advising services of the College of Pharmacy and the College of LS&A.
I know of one person (it's a handful of students and I'd assume a good proportion of them drop out because high schoolers often don't know what they really want when applying to colleges) who completed the program, but he said it was difficult to get the required grades. This program, however, does not force you to complete your University of Michigand undergraduate degree.
