IU vs UCI vs U of South Carolina

I am an international student form india and have got accepted in following courses
UCI business economics
IU Bloomington business (not direct )
University of south Carolina (pre-international business)
weather is not a problem for me neither is tuition
what does pre-international business mean ?
which course would have better prospects ???

Pre-international means you have to have certain courses and certain grades to continue to upper level. Entrance to IB is not guaranteed. Look at the website for more information. A good question to ask there is what percentage of pre-IB students make it to upper division.
