Hello, 

Cut off for any college depends on the difficulty level of the entrance exam, performance of other applicants in the exam and the number of seats available in the college. According to previous year cut off marks for general category students was 130 for Assam Engineering College, Guwahati; 120 for Jorhat Engineering College, Jorhat; 115 for Jorhat Institute of Science & Technology, Jorhat; 115 for Bineswar Brahma Engineering College, Kokrajhar. 

Hope this information was helpful.

Good luck!
