Class 12-science

Well, all the fields have their own scope and space of work and opportunities. Choose the area of specialisation you are interested in and good at. In my personal experience, I have seen how engineering is one of the really good and prosperous courses to pursue with good job offers and diverse career path. Alternately, you may consider Bachelors in science with subjects like chemistry, biology, mathematics, food technology, agriculture and biotechnology. Corporate and educational sectors; private and public sectors all of them open arms with job offers.
