Also want to highlight one more point here ...One of the classes in Mumbai has set up a Whatsapp group where they are discussing CAT questions and the head of the classes is solving the cat questions and distributing the solutions. ...One of my frnd who is into that classes was asking for CAT questions to post in tht group and obtain solutions but i declined. also the most disheartening part of the story is the classes belongs to one of the most respected and talked about aptitude guru, successive CAT and CET topper of past years.
Request you all not to share any details of your CAT questions to the friends from that classes (if you are able to guess from the hints) because if your frnd gets it ..he/she will post it in the group and the head of the class solves it and circulates the solution to all...which is absolutely unfair even if it does not help them ....lets us please act responsibly if others are not ....also @sir of the above class (as you are also quite frequent on PG) ..if you are reading this post kindly refrain from continuing activities like above Whatsapp discussion.....I hope you understand the relevance of fairness in the system ... @pagalguy @laj ..I hope I am not violating any PG norms here, kindly guide me on that.....sorry for hurting any sentiments 😐
Also Puys as soon as You see a CAT question which was asked in your slot on this thread or anywhere in PG...kindly report it immediately to PG,
