If you start at a four year school, choose an affordable one that you are willing to graduate from.
If you start at a community college to save money or some such, plan your pre-med path carefully so that you will have some BCPM courses at the four year school. If your major is something like biology or chemistry, that will happen automatically, so not a lot of additional planning is needed besides making sure that you include additional pre-med courses like biochemistry, statistics, psychology, and sociology among your electives. If your major is something else, you may have to plan carefully and take calculus, physics, and general chemistry at community college before transfer, and biology, organic chemistry, biochemistry, and statistics after transfer to ensure having enough BCPM course work at the four year school.
Obviously, in all cases, you need to get all or almost all A grades at all colleges to get past the medical schools’ initial GPA screens before your application gets read.
