To get into an associate degree program in biomedical engineering, most colleges and universities will require a high school diploma or a GED equivalent. Besides that, most schools will need you to have taken three courses in math, algebra through trigonometry, and one course each of biology and chemistry. If you do not have the required courses in your high school record, or due to academic deficiencies, couldn't clear these subjects, you can always take preparatory courses available at some colleges.
