Lehigh is a bit of a stretch but a very reasonable risk. Lafayette and Union a bit easier. Skidmore you are a bit above average.
If you applied to all five I would wager you get in Skidmore and St. Lawrence. I wouldn’t bet against Lafayette or Union. I might bet against Lehigh.
All things considered, you could take some additional intelligent risk. Especially because the five schools have good aid and merit in the case of St. Lawrence.
More importantly, have you visited any of the schools you are considering?
