Regarding Mr.Rajesh Aldarthi's discussion I have a doubt. Specialisation in many branhes of scince,commerce or arts whatever it may be is it possible to study entire subject in one semester? for eg.Chemistry, is it possible to learn about the subject in deapth to know the structure of any compound?. Upto what extent university has to incorporate? interviewer may ask more than that if he comes to know he/she has taken that particular subject as a specialization.
