Dual Enrollment and qualfied eduation espenses for IRC 529 and AOC or LLC

My grandson is a junior in high school but attending full time college classes (12 hrs) at the local community college. This is his first semester.  He has tuition expenses of $1890, scholarships of $567, and related waivers of $953; netting to $370 due. A number of other charges are listed for books, tuition, mandatory fees, etc., but they are all waived.

 

Tuition is obviously required for his attendance in classes at the college.

 

Questions arise as to the eligibilty of the tuition as a qualifying educatiion epense for 529 purposes. A questions also arise as to whether room and board expenses up to the Cost  of Attendance for a student living with parents would qualify.

 

Similarly, questions arise as to the eligibility of such costs for the American Opportunity Credit (AOC) and Lifetime Learning Credit (LLC).

 

Any guidance would be appreciated.
