hi,

see cutoff score depends on some determining factors like number of applicants, questions difficulty level, seat matrix, students category , choice of stream etc , now see every year amrita vishavidyapitham conducts AEEE entrance test, seats are reserve for open state and state wise quota. so based on previous years data if you belongs to state quota you have moderate chances for cse at coimbatore or amitapuri, but for open state quota it seems difficult to get cse in either of the campus.

you may follow the below link to know in details about previous years cutoff:
