M.Sc Chemistry

First of all, both are the Bachelor degrees but B.E is having more craze now a days. By doing B.E, you will get a job or you will start your own business. The jobs for B.E is everywhere. But for B.Sc. You need a particular place where you have to do a job. Very less industries, laboratories, offers the job for B.Sc. So you have to go for B.E. Best of luck for your future and if there's any query, feel free to ask.

Hello dear,

Leave a query on online mode, they will probably call you back and guide you better. There is no such barrier for other state level candidate.

You can take job in a company requiring strong background in mathematics. If it is applied Maths, it will be very useful. Also, you need to learn a bit of coding. Applied maths + coding, a job will be pretty much guaranteed in any company and/or startup looking for someone to do some research oriented project. With experience, you can become pretty good in coding. Also try to publish at top venues in your field.
