Hi All this is the info I have collected from net.
Seems like its quite similar to GATE exam and majorly includes subjects as C, DCS , FCS, Automata, Probability, Permutations and Combinations, Alogirthms and Data Structures, Circut And Systems, OS, Internet Info Like TCP/IP, Ethernet..etc..etc..so pre much like
GATE Exam
