I have been to 4 info sessions and have never heard about a quota for out of state students. In fact, I believe it is not allowed for state schools to have a quota for out of state students. I have only heard of them having a minimum quota for in state students since a majority of its budget comes from state taxes. I don't think that statistic is correct.
Also, at the info sessions in November, January and march it was stated that the new Pre-reqs affected the amount of applicants. They were not announced until October 2012 and since you can only have 2 Pre-reqs in progress when you apply in Spring, you would have to already have them, be done with all other Pre-reqs so you could take them Spring 2013 OR take them in Winter 13. They also changed the minimum grade for a Science Pre-req from C to B so a lot of people who were planning on applying no longer can.
There are further changes for Fall 2014 so I highly recommend attending an info session if you want to apply to Hunter and check their website often.
