F&M, Laf, and Lehigh are probably the most selective schools on the OP’s list. One thing to be aware of at schools like these is the growing reliance on Early Decision in admissions. It’s not unusual now to fill roughly half of the freshman class by ED. So if you apply RD, assume that half of the available slots will already be gone by the time they start reviewing your application.
For example, the latest Common Data Sets (for Fall 2017) show the following numbers:
Lafayette: 680 entering freshmen, 335 ED admits
Lehigh: 1,234 entering freshmen, 669 ED admits
F&M: 645 entering freshmen, 346 ED admits
It’s likely that a small number (<5%) of ED admits reneged on the ED commitments, but even so, it’s clear that the ED admits represent approximately half of the entering class.
At F&M, the ED acceptance rate was 61.9%. By subtracting the ED numbers from the totals, we can infer that the RD acceptance rate was only 31.6%. Clearly the system is strongly biased in favor of ED applicants, who now comprise the majority of the class, as per the numbers above. Not saying that this is a good thing, but it’s something to be aware of.
