Science

Eligibility to pursue Masters in environmental science is mentioned below:
- Students must be passed Bachelor and Degree from any recognised University or should be equivalent examination with any of the following subjects like environmental sciences, chemistry, botany, zoology, microbiology, geology, geography, life sciences, fisheries science, BE(civil engineering), environmental engineering, agriculture, physics, biotechnology and secured minimum 50% marks (45% is case of SC/ST candidates) in the above mentioned examinations.
- Candidates who have appeared or who are likely to appear for the qualifying examination i.e. B.Sc. or equivalent but whose results have not been as yet declared can also appear for this entrance test provided they have offered the mentioned subjects at the said examination.

An aeronautical engineer is crucial in the research, design, development and performance testing of commercial and military aeroplanes and weapon systems. Aeronautical engineers improve flight safety and fuel efficiency, develop control systems, analyse new materials and use advanced technologies to meet customer needs and reduce the environmental impact of air commute.
Coming to the next question, scope of aeronautical engineering in India. This is a difficult question to answer in every aspect, of course, you get a lot of opportunities in government sector but it isn't enough. I guess nothing is enough and that shouldn't stop you from taking up this course or profession if you are passionate about it and things involved interests you.
What all can I do after aeronautical engineering?
Maintenance of Aircraft - aerospace engineers test new aerodynamic and aviation systems, and maintain them.
Aircraft Designer - aerospace engineers specialising in this field deal with designing, constructing, and testing aircraft, missiles, and space crafts. They may conduct basic and applied research to evaluate adaptability of materials and equipment to aircraft design and manufacture.
Aviation Engineer- aerospace engineers in this field deal with the airport design, aircraft navigation technologies, and aerodrome planning.
Defence - aeronautical engineers in this field deal with creation, maintenance and deployment of defence aircraft such as fighter jets, choppers, bombers, etc. Also, the job requires being able to handle such aircraft at necessary times.
Where all can I work?
As everyone here mentioned right, you can work in the government sector with ISRO, DRDO, HAL, etc. And then we can look at private companies such as L & T, Godrej & Boyce Aerospace, Boeing, Airbus, Mahindra, etc
You can also go for Indian Airforce and Indian Navy.
I hope, it will help you.
