I think you’ve gotten some good suggestions on potential colleges. Now I urge you to open up a bit to the advice you didn’t want to hear. The most important part of a good college list is fit. Understood the No 1 criteria is affordability, but I think you really need to look at whether an LAC and the requirements for intensive reading, writing and class participation is where your child will be comfortable. I worry that you are betting on a magical transformation to motivate your son to want to learn and succeed.
What is he doing now to demonstrate he wants to go to college? Is he working to save money? Writing essays? Taking an academic enrichment class?
My point is spending time finding an easy college for a non-motivated kid may not be addressing the real issue. I would really encourage you to get your son front and center on the college process. He needs skin in the game.
