Pros
Good material, of course you can buy many ouside with 10% cost(but very limited available solutions for that)
If you are lucky/K01 batch, you might get good teachers
(but few are extremly egoist)
Cons:
No solid plan to finish 2nd year course well before exam date
hence revisions are hurried(where chaitainya finishes them atleast 3months before)
Even if you are promised transportation, that might be removed anytime then you have to make your own arrangements
Many times on holidays, Management would call students for class, but then they declare holiday the moment students reach school(not sure why)
Infrastructure for All india test is a pathetic, very limited seats in kukatpally locality and those seats are over within one hr of opening for registration, resulting students to travel long distance to some other place
