Vikas,
Tough to be in your shoes! With those stats, I'm sure you'll earn interview invites, but they may be for the waitlist (or maybe not)! But I'm 100% sure that you'll get more invites from either U of M, Nova, and/or Temple (mostly likely be for the waitlist though)!
$3000.00, WOW!! Might as well send it in. You know, in this late of the game, I would just send in my BU deposite and secure the seat and go there next year! Why bother looking at other schools when they all are taking their sweet old time looking at applications that are already in their possession as classes are being filled.
For example:
Temple, just talk to the admissions personal two days ago to check up on my application status and at the same time I inquired about the class number status. Exact words, "We currently have over 90 deposites!" If you do the math, 125 seats minus 90 deposites = ~35 seats may be available. You might say, well, someone will drop out on the deposite list once their number one school choice sends them an acceptance, that's correct, but at the same time, there are probably still a good over 50 applications minimally being reviewed currently (I'm guessing)! With your submission time frame with AADSAS, Temple may not even get your AADSAS for another week or so!
Nova, when I was told that I was invited for my interview via phone last week, originally I was told that the interviews were already scheduled into mid-April and that would be the soonest! Granted someone may drop their earlier interview dates from here and there, but it's not guaranteed. I was fortunate enough to snag an earlier date, but who knows if you will be as lucky even when you do get invited for an interview! If Nova does not have your complete application now, I'm afraid that you may not hear positively from them until late March or even into April! By then, what do you think the class of 95 students filled status will be like? SU-Ann, the admissions coordinator tells me all the time that they are "swamped"!! I got a feeling that Nova is a little slow on things!!
Man, I would just go to BU and be happy! Paid that $3000 and know that I won't forfeit it! BU is a good school! Not to be pessimistic here, but it's a timing game!! This is all my $0.54!!
I do sympathize!
