The first two years of a typical college is normally just a rehash of high school material. It’s wasteful for the students – but profitable for the colleges. Dual Enrollment is the answer. Learn something once, and learn it for free.
In Georgia, they have a program called “Move On When Ready.” It allows students as young as 9th grade to take college courses. In Texas, it’s usually 11th & 12th graders, although younger students are allowed a couple of college courses too. Other states may be as generous. Be sure to check out your state.
