Dear Candidate ,
Your cousin , with 93 % in Tamil Nadu state Board and a 51 percentile in JEE Main , has a a fair chance of getting admission to the ECE branch at SASTRA university under stream 2 . Stream 2 admissions are based solely on class 12 board marks , and since she has a strong academic percentage, she stands a reasonable chance , especially for ECE , which is generally slightly less competitive than CSE . While stream 1 is more competitive due to inclusion of JEE scores ,  her JEE percentile is not high enough to secure admission through that route .
