StanfordSon is obviously tro****lling.
@OP, what exactly do you expect us to tell you? Nobody here is going to have an accurate answer for you. Apply early if you think the program is a good fit. They accept a number of students from New Jersey, and it is not unheard of that they accept more than one person from the same school (it’s happened recently with TAMS and TJHSST). Nobody here has any insight into how the M&T admissions process works; not even me as a recent M&T graduate.
