ISL is an athletic league, and the schools are quite different in terms of rigor, for example. So part of the answer depends on which ISL school you are coming from.
Where kids go can be influenced by whether they are athletes, full pay, legacy, etc., so your CC can probably help you better understand destinations of alums in that context if you are trying to set expectations based on history.
Your odds might be improved by looking at schools in the Midwest, or even the mid-Atlantic, rather than New England.
Really, though, what matters most is what you are looking for - from major to size, geography, etc. Start there. My guess is your school has a good questionnaire for starting the process. Use the resources you have available to you.
