If you study then the DGCA exams are easy to pass... There are basic questions in what they ask and you should know the answers if you are a pilot... If you observe most of the students who fail are chavs... Yes there are few students who studied and failed because they messed up few questions in DGCA but they pass the next time...
The problem is when the non- IR guys are asked to pass the exams (which is the case with helicopter pilots)... The heli guys are asked questions about fixed wing...But even they pass after studying... So, there's nothing scary about these exams...
And yes a bit of guidance does help for sure...
Good luck...
