Selective school are very expensive and all use different formulas for looking at awarding aid–which can be substantial!
I recommend the College Aid Pro website for learning about and comparing the cost for college to your family specifically.
You can enter three schools for free, or enter many for $4.99/mo. Worth it for a short period of time!
They also have a great, filter-able list of scholarships. They list all the merit scholarships a school offers and projects costs for all four years which is super helpful.
You should not need to buy any further consulting from them as you can find all the information you need online.
