Hello Aspirant!

• Govt. of India reserves a few seats in Engineering/Technology/Architecture/Pharmacy courses in AICTE approved institutes across the country.
• The seats are reserved for students belonging to 12 North East States and UTs namely Arunachal Pradesh, Assam, Meghalaya, Mizoram, Manipur, Nagaland, Sikkim, Tripura, Dadar & Nagar Haveli, Daman & Diu, Andaman & Nicobar Islands and Lakshadweep.
• These seats are reserved because these states and UTs do not have engineering colleges/polytechnics or have lack of facilities for education in the specific field of technical education and for certain categories including foreign students.
• To have the maximum possible participation of eligible students, MHRD has taken a decision of conducting seat allotment on such seats through a Centralized Seat Allotment Board for North Eastern States and Union Territories (CSAB NEUT). 

Hope this helps you :)
