Iowamom ... My son did what your son is doing. He entered college six courses into his freshman year. He had to catch up four to graduate in three years. He emphasized while playing summer ball he had the focus and made the time to take the other four classes online. He had summer ball and summer school on his resume at the same time.
The team required all players to volunteer in the community even if it wasn’t much. Visiting a hospital, senior home or school once a semester was enough.
The reality is if your son has remaining eligibility, has decent grades and doesn’t screw up the application process he’s in.
