Mr. K.K.Jha conduct separate doubt clearing classes at your home or his centre. Mr.Jha is available in specific allotted timings (from morning to evening) at specific location for Doubt Discussion Classes.
you already know coaching like FIIT-JEE, VMC, Aakash,Bansal, Reso, Vibrant, Allen, Career Point etc. They have these assistant teachers who also attend the lectures with students and can provide some help with doubts later when the core teachers are unavailable (which is almost always).
But to be honest anyone is hardly interested. They all eye the students who could produce top AIRs. More than often they will not have time to entertain you.
