i am asking you that is it necessary to start preparing for iit-jee in specialized coaching centres like rao iit,fiijee. or is it better to learn and syudy physics,maths,chemistry at depth and then join specialized classes. or is there any oher option you can suggest

sahil,

 it is good if you try to prepare by taking coachings. but if you are thinking that taking admissions in coaching will just do than you are wrong. you will have to give same effort in any case the faculty in coaching can only guide you but can’t study for you. you will have to study yourself. if you are a student like me ( i want to study but after seeing book it become difficult to decide what should i study) you should better join a coaching. else tutuions will do .
