Hi kashking,
There are a number of different factors that will impact whether you'll receive an invite to attend any particular Program. Rather than talk in general terms, since you are interested in applying to some highly-competitive Schools, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement (and the more time that you have to act on that advice, the better). There's a Forum full of those Experts here:

2) What specific application deadlines are you facing?
