Schools generally release the new questions in the summertime, although it varies from school to school. The best thing to do is to contact the admissions office of your target schools and talk to someone directly. Most b-school applicants are shy about identifying themselves in the process, but the fact is that it usually helps to establish a relationship with them. REach out, identify yourself, and develop some contacts in admissions and you will not only be getting direct information, you could potentially nurture a relationship which will help you when you apply. Good luck.
