Many students believe that the way to a BS/MD program is to take as many college level courses as they can before they finish high school. If you have exhausted all of the classes in a subject that your high school offers, then taking a college class is a great idea.
But, I work with many students who were successful getting admitted into BS/MD programs, including programs like HPME and PLME, that have never had a college level course. So don’t think you must take a college level class to be competitive for a BS/MD program.
Taking too many college classes can actually hurt your chances of admission to a BS/MD program, for this reason many people like to go for what’s safe, and just get an online policing degree. The problem occurs when students decide that they want to earn an associates of arts (AA) degree in college. This may sound like something that would impress an admissions officer but in fact, it will disqualify you from a BS/MD program.
BS/MD programs are designed for current high school seniors. Even if you are a senior, if you have earned a degree in college, typically an AA, then you will not be considered by most BS/MD programs. The reason is that most colleges will treat an applicant with an AA degree as a transfer student not as a high school student.
If you want to take college level classes as a supplement to classes at your high school, fine. If you want an online construction management program, fine. But don’t fall into the trap of going too far and getting an AA degree.
