Realistically, few students get off of most waitlists. Stay on all of the waitlists, but don’t get your hopes up too high.
F&M admitted 31 out of 1,330 on the waitlist last year: http://www.collegedata.com/cs/data/college/college_pg02_tmpl.jhtml?schoolId=1171
Dickinson admitted 10 out of 260 on the waitlist last year: http://www.collegedata.com/cs/data/college/college_pg02_tmpl.jhtml?schoolId=1155
Brandeis admitted 40 out of 615 on the waitlist last year: http://www.collegedata.com/cs/data/college/college_pg02_tmpl.jhtml?schoolId=453
Rochester had 808 on the waitlist last year and may not have admitted any: http://www.collegedata.com/cs/data/college/college_pg02_tmpl.jhtml?schoolId=117
Make plans to start at a community college and investigate what courses you need take there to prepare for transfer in your major at your transfer target schools.
Of course, you can investigate whether there are less selective four year schools with late application deadlines. However, scholarship deadlines may have passed even if the deadline to apply for admission has not.
