I think if OP reads through all these posts there’s enough information to see many possibilities and ways to prepare a kid to graduate from college early.
We focused on keeping doors open for our kids as they went through high school. That goal is best served by being informed about the options (and how to pay for them) and knowing your own kid.
Our oldest will graduate with a bachelors and masters in 4.5 years ( would have been four but she changed her masters late in the game). Kid two will graduate in three and study abroad twice if things continue as planned. One study abroad was a summer and earned two classes of credit, so technically 3.5 years. Both had a bunch of AP and DE credit— kid one had more. Kid three hates high school a lot more and only wants to do music, so we are holding academics together and learning how to further his music talents in college. I think it will take all four years for him.
