I've been in trying to pass my CS Executive exams for the last 3 years but still no success. In my first examination I passed in 2 subjects so I was pretty confident that I will pass in my next attempt but still I was cautious enough not to slack off.

After that my marks has been degrading and now I'm not even passing 1 subject. I've asked multiple seniors about my answers writing pattern and there is always 2 answers, either I'm going in good direction or I'm in wrong direction.

I've seen some of my seniors going more than 3/5 years in executive and after that they somehow crack it. I don't want to take that much time and getting demoralised in this as I want to stand on myself as early as possible.

Any advice on how to prepare and getting proper mentality or pointing out the criticism in my part is well appreciated.
