<p>Well, the terminology being used is confusing things a bit. I consider safeties to by synonymous with liklies or safe bets. The OP is using the term likely for what I think is what I would call her match/ballpark schools.</p>
<p>The word “guarantee” is tricky as unless a school has a 100% admit rate, nothing is a guarantee. However, a safety or likely or sure bet school (take your pick on the semantics) should be highly probable.</p>
