A. Yes. The Treasury Department clarified in 2013 that all college and graduate students can qualify for subsidized insurance on an exchange — as long as they don’t enroll in the university’s plan.
There’s no one-size-fits-all solution for college students. In your situation — since you’re eligible for a subsidy in the exchange — it’s likely cost-effective to purchase an exchange plan instead of the student health plan from your university.
But for students who aren’t eligible for a subsidy (which is often the case if the student is still claimed as a dependent on their parents’ tax return, and the parents’ income is counted for subsidy-eligibility purposes), the college’s health plan may end up being more affordable.
Whichever option you choose, the coverage will be fully-compliant with the ACA. Student health plans are required to comply with all of the ACA’s individual market reforms, as are all individual major medical plans — including both on and off-exchange plans.
