M.Sc

I'll try to put a better answer. I think this question must be raised in every mind before becoming a part of any B.Sc. batch at BHU. One thing is very common in students enrolled in B.Sc.(Hons) at BHU, That all have prepared for Medical/Engineering entrance examinations. The worst thing with these guys is, they often don't know what is the difference between science and engineering/medical. Scope in any subject and the possibility of employment through the subject are two different topics. Therefore, before getting admission in B.Sc. at BHU, it is very important to know what you want to get through B.Sc. and what you want to do after B.Sc.(Hons.). Once this decision is made, the next thing is to get yourself out of the inferiority complex. What kind of inferiority complex ? So don't compare yourself/your courses/your Institute of science with other programs (B.Tech. B.E. )/premier Institute like IITs and others. As a student of the Institute of Science, you have an identity and characteristics.
Now come to the point. I dont know the subject( and subjects combination) you are going to choose as your Hons. Therefore I am going to explore all possibilities. Since I dont have any experience in Bio group so here I can answer only for B.Sc.(Hons) Maths group.
Let there is no any subject of your interest and not looking for research(or career in academics), your maths is above average and you are only seeking a job. Then you can-

2)- Choose Chemistry Hons(Subject Combination PMC ). Done your B.Sc. Chemistry. Write JAM/BHUPET>Get admission in M.Sc. at IITs/BHU> try to Get Placed in any relevant profile after completing your PG degree. In the last semester of MSc, You can also write GATE, using GATE score you may be placed at PSUs like ONGC and other. Gate score can also be used for BARC recruitment of Scientific Officer.
