Have you and your parents run the net price calculator on each college of interest?
Have you and your parents considered the cost of medical or dental school (since it looks like you are pre-med or pre-dent) in your financial planning for your education?
Have you considered what your alternate career plans are if you do not get into medical or dental school? Biology graduates do not have that high paid job prospects, so taking a lot of debt for an undergraduate biology degree is not a good idea. Note that any undergraduate major is ok for pre-med or pre-dent, if you complete the pre-med or pre-dent course requirements as well (biology is merely convenient in overlapping with many of these course requirements).
