Thanks Respected Member for your reply. My Background is BS Electronic Engineering having a good CGPA. I graduated last year in March. I purchased books last year registered for CE-17 but did not start preparation. I cannot self study mainly our home is quite occupied as guest and relatives visit or stay quite often. I cannot study with constant commotion and disturbance as bell ringing and do this and that. I need a silent place to study. For job tests I prepare on my own in my home.
