Declining Admission, When do you do it?

It’s coming down to three ‘finalist’ schools for S20, but he is waiting to hear about programs within those three schools before he makes a final decision (extra merit scholarships/ research fellowships etc.). I think we don’t get the final pieces of the puzzle until mid-late March- so will hold off until then. At that point, I’m envisioning that we are sitting around the table debating pros/ cons/ cost etc before he makes the final call.
