Petroleum Engineering

Obviously go for Diploma.
The Diploma course has a semester pattern similar to that of the degree in engineering. Hence, Diploma students adapt to the pattern more easily as compared to those class 12 students who have followed a yearly examination pattern and find it difficult in the first year to appear for examinations of six subjects within the first four months of the course.
The discomfort is evident through the results of first year of engineering across colleges, with even the usually bright students scoring really low and a few others having to take a drop of one year due to failed scores in more than five subjects. Diploma students by virtue of being admitted directly to the second year, bypass this first-year hurdle.

Hi Ben,
All the branches of engineering are equally good and have tremendous job opportunities. It entirely depends on how well you understand and handle the stream and increase your scope of growth. Different branches of engineering are popular at different places and the popularity depends upon the day to day requirement of that place.
Mechanical engineering is one of those fields which offers good career prospects.
A degree in MS mechanical engineering will surely enhance your job profile in India as well as globally, but please remember getting a job depends entirely on the knowledge level and caliber of the students.
Petroleum engineers are employed in jobs which are mainly concentrated in oil and gas extraction, professional, scientific and technical services and petroleum refining.
One can also entail the option of working as a scientist/researcher to carry out the R&D processes. Employment is rest assured for graduates in this sector as the number of graduates passing out is always less than the number of jobs available.The demand for petroleum and petroleum products is only expected to increase and the increase would lead to creation of new jobs. In fact, there is great demand of efficient petroleum engineers and almost every young graduate in petroleum engineering gets a job offer from petrol and gas companies from India and overseas.
I hope this information helps. Please feel free to revert.
Wish you luck.
