Qualification for all the above exam is B.Tech/B.E. pass out. for some type of PSU exam final year student are also eligible like BEL,NTPC,DRDO etc.

i gave only BEL exam held on 26-6-2011. the question paper was very simple but time management is important in this exam 150 question in 150 min.

According to me best book for bel are...
1 for engineering part MCQs in COMPUTER SCIENCE, timothy j williams
2 for aptitude/reasoning B.S. grawal
