You have a couple overlaps with my D24, so I’ll chime in. I spoke to FA officers at both Bowdoin and Swat this week. Bowdoin indicated that its financial aid package does not include health insurance, which would cost us an additional ~$3,000. Swat’s financial aid package also did not include health insurance, but I was told that it would only cost an addition $200-$300. (Now that I write that, I wonder if I misheard.) We also have the option of keeping D24 on my current employer-provided health insurance.
Anyhow, my point is to talk with your parents and the financial aid offices at each school about health insurance, as it may or may not be a large additional cost.
