Mechanical Engineering

Hi,
Mechanical and electrical engineering are core branches of engineering.
Mechanical engineering is the discipline that applies the principles of engineering, physics, and materials Science for the design, analysis, manufacturing and maintenance of mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery. It is one of the oldest and broadest of the engineering disciplines. Mechanical engineers are employed in operations and Maintenance roles in manufacturing and services industry. It is an evergreen branch with no cyclic trend in job market.
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. Electrical engineering has now subdivided into a wide range of sub-fields including electronics, digital computers, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing, instrumentation and microelectronics etc.
Electrical engineers are employed in operations and maintenance roles in manufacturing and services industry. Electrical engineers are also employed in electrical power generations such as atomic power plants, hydel or thermal power plants. Electrical engineers are also employed in power distribution and services companies. Job opportunities for electrical engineers are available in both private and public sector like railways, civil aviation, electricity board and utility companies, electrical design and consultancy firms.
In addition, mechanical and electrical engineers can join Indian Engineering Services, DRDO, ISO, Defence and paramilitary forces also. Mechanical and electrical engineers are also employed in teaching and R&D besides working as independent consultant.
Most of engineering college's admission in mechanical and electrical engineering branches is based on entrance examinations after 12th with PCM subjects. You may refer to following link for information on all engineering colleges offering B.Tech mechanical and electrical engineering degree courses:

Pilot Astronaut minimal requirements:-
Pilot astronauts need a minimum of a bachelors degree in engineering, biological/physical sciences or mathematics. They also require a minimum of 1,000 hours pilot-in-command time in a jet aircraft.
Pilot astronauts need to be able to pass a NASA space physical, which includes the following items:
Distant visual acuity: 20/100 or better uncorrected, correctable to 20/20 each eye
Blood pressure: 140/90 measured in a sitting position
Height between 62 and 75 inches
For applicants applying to be Pilot astronauts, NASA strongly recommends flight test experience. While it is theoretically possible to obtain these credentials without going into the military, the majority of NASA Pilot astronauts come from either the Air Force or Navy.
Mission Control Astronaut Minimal Requirements:-
Mission Control astronauts are required to have the same education as Pilot astronauts: a bachelors degree in engineering, biological/physical sciences or mathematics. However, Mission Control astronauts must also have at least three years of related, progressively responsible, professional experience in their chosen field of study. Advanced education is highly recommended for both Pilot and Mission Control astronauts, and can even replace some of the three year work requirement. A masters degree is equal to one year of experience, and a doctoral degree is equal to three years of experience.
Mission Control applicants must also be able to pass a NASA space physical including the following items:
Distance visual acuity: 20/200 or better uncorrected, correctable to 20/20, each eye
Blood pressure: 140/90 measured in a sitting position
Height between 58.5 and 76 inches
Payload Specialist Astronaut Minimal Requirements:-
A third and far less common path is that of a Payload Specialist astronaut. Payload Specialists are non-NASA personnel who are brought in to perform specialized onboard duties. They can be brought in from private companies, research universities and even other countries. Although they do not undergo the NASA astronaut selection process, they are required to have an appropriate education/training for their payload or experiment. Of course, they must also be physically fit for space travel. Payload specialists were far more common on the Space Shuttle missions than they are now on the Soyuz missions, due to the larger crew capacity of the Space Shuttle.

The average package of my college ranges from Rs 5.5 lakhs to Rs 6.5 lakhs. Even if you are an average student doesn't matter, because average students are sometimes proven to have a good placement record . Hope your percentage is 60% and above in SSC, HSC and Graduation. If not then at least it is needed to be above 50% for getting admission in the Mumbai campus. Placements in MBA colleges are done solely on the basis of the skills a candidate has in him or her and secondly on the academic records which a recruiter sees while hiring candidates for the jobs. Even I was an average student during my school and junior college days. You just need to show your interest and nothing else in doing MBA, rest you will make your own way.
