[MS Ad] [ MIS@UPitt]

Dear ***,

The School of Information Sciences at the University of Pittsburgh is pleased to extend to you an offer of provisional admission to the Master of Science in Information Science (MSIS) degree program. A provisional admission means that you have not yet met all of the admission criteria. If you choose to join us at the iSchool, you would enter the Master of Science in Information Science (MSIS) program in Fall Term 2012 (131).

As a provisional student, you will need to satisfy the conditions listed below before your status can be changed to full-student status. Provisional status has absolutely no reflection on your ability to pursue graduate studies.
To inform us of whether or not you will accept this offer of admission, please submit this Admission Offer response form by */*/*. A copy of this Offer of Admission will be sent to you via the U.S. mail. If you have any questions about admission, deferment (changing term of entry), or enrollment, please contact us at.............

请问大家，这个provisional admission是什么东西啊？这个和我们一般的Ad有区别吗？谢啦！！！
