While you are learning the lay of the land, learn what a safety is and is not. Check out this thread from today

People who think highly-selective schools are safeties don't really have any clue what a "safety" needs to be: kid would want to attend if not admitted elsewhere, kid is
certain to be admitted, and the college is certain to be affordable.
The Harvey Mudd example above in this thread is DCUM idiocy at its finest. Admission is nowhere in the ballpark, or even on the same planet, as sufficiently certain for
safety territory. (And no, I don't care what their TJ Naviance scattergram told them. Eventually, those end up being the stupid examples of "I didn't get into my safety."
Admission safety: stats >75th percentile for the college (admission stats, i.e. test scores and grades, are published on the college's website) AND acceptance rate >50% plus, as noted elsewhere, no major reliance on subjective factors like demonstrated interest, no yield protection.
Targets/matches will be somewhere in between reaches and safeties. Mudd is an example of reach-for-all-applicants due to the low acceptance rate.
