Recently, Kaysons Education (http://www.kaysonseducation.co.in/) has been using my name to publicize their products which I never used. For example, they are selling the "Make Me IITian" package (http://www.kaysonseducation.co.in/Make-Me-IITian and http://test.cleverserver.com.ua/Make-Me-IITian) , which was NEVER used by me. In fact, it wasn't even launched when I appeared for JEE.
Moreover, they claim that I solved 13,500 problems from their package (http://www.kaysonseducation.co.in/guidance/jee-advance-2013-cut-off/ - observe how they have highlighted AIR 127 and not AIR 33) , which is entirely false. I have never recommended people to solve problems from Kaysons Education material because I myself never used it to solve problems. I used it only to view lecture videos (that too partially).
To quote another example - http://www.theguidance.co.in/result-2014.html
In the above link, they claim that Shubham Yadav got AIR 98 in JEE 2014, which is totally false. Firstly Shubham Yadav wasn't in any way associated with the guidance classes. Secondly he gave JEE 2013 and not JEE 2014.
I request you all to rather spend your parents' hard-earned money on books rather than on packages which are falsely taking the name of IITians to promote their products.
You can find some good books here
Be wise, be smart. Do not be fooled by false advertisements. Make a wise decision.
Finally, to conclude, I would say that students should not believe in any advertisement claiming my name other than what I have mentioned myself on the blog (FIITJEE and Resonance, with whom I was officially associated).
