Hmm if u talk about the coaching material of Narayna then I can say that Narayana's material is compilation of all the other packages that other coaching institutes provide. So it is a good material. I have seen it and can say that it is worth reading. However here I must comment that our study material will be soon on the site and it is definitely much better than any material which any of the institutes provide.

 

Now about the faculty. The faculty is also good, infact many of the FIITJEE faculty has joined Narayna. But u must remember that it is u urself who would make the difference. Any teacher can just help, rest is all on ur hard work. :)
