Was a recruited swimmer right here class of 2020 swimming for vassar college next year. Hate to break it to you but the schools you listed will not recruit you as you will need at least junior national times (47 100 free, 59 100 breast). From my opinion, swimming diii in general does not give you a huge boost as you will still need to go through a pre-read. This means admissions must give the coach the green light that you are admittable. However, diii is not guaranteed admission as myself and many others were deferred when we applied ED1 despite having a positive pre-read (wesleyan was my ED1, vassar was my ED2). As a reference my times for those same events are 50 sec 100 free and 1:02 100 breast.
Schools that you would probably be able to recruited at:
Vassar
Wesleyan
Hamilton
Trinity
Hope this helps.
