  2. Sir i have brought a practice set for IT officer which is published by Arihant Publication. In this set the professional knowledge is very different type. It's like a general computer knowledge. And in many other sites other types of question is given related to IT field. So I am totally confused about professional knowledge which is asked in IBPS SO. So, please give right advice so that i will perform well.
    Thank you

  5. I appreciate your point from bottom of my heart mam, but it is also true that bribe is also playing a vital role for unemployment of many meritorious student and every exam is getting more tough day by day..it is true and nobody can escape from it.
    Approximately 99% of my neighbours who got job in this five years have got their job with donation.so I have a request to all the students please take any strong step to stop the education mafia. Because it will become very dangerous for our future. Plz suggest me what should we have to do in this case.

  64. Don't cherry pick special cases please. Search for the cutoffs in any competitive exam and by and large you will find that General cutoffs are always significantly higher. Its only logical since 90% of people fall in general category, yet only 50% of the seats are allotted.

    ReplyDelete
  65. Completely agree. Reservation in everything as totally destroyed this country and has made life very easy for the minorities and reserved category people at the expense of general population.
