If you do Touro you can do undergrad in 2 yrs including summers. You can do a CUNY in 3 yrs. Also, yeshiva degrees are getting accepted less and less at med schools and dental schools especially so you may want to think about getting a normal degree. You also have to rock the DATs in order to be competitive. And if you have a yeshiva degree you really need to destroy it. Dental schools range from 20k to 70K a year depending on state schools and private schools. Also depending on the state if your a non resident then you usually pay the first yr out of state tuition then the next 3 yrs is in state tuition (about half price)
