well im not exactly sure if this is what you are asking when referring to "matriculation time", but after you are accepted you have 1 month to put in your deposit (which I believe was $1000 for me last year). There are various other deadlines throughout the year (and fees) to confirm that you are coming. But the fees go directly to tuition, so if you do end up matriculating you have already paid about 2000 towards your first quarter tuition. Anyways, hope that helped.
