Mechanics

Hello there,
I was going through the same question after getting my WBJEE '16 result and at last, I think I have taken the perfect decision. There are few parameters by which you can compare between KGEC and JGEC:
1. Opening & Closing rank
If you go through some research in the web you will see that KGEC has lower or crores (up to 4k) comparable to JGEC (crores was more than 5k) in the past years. KGEC comes just after JU under WBJEE.
2. Streams
JGEC has a extra stream I. e CIVIL, which KGEC does't. So if u want to study CIVIL only then JGEC is your only choice but if you are looking for others you have both the colleges.
3. Placement
Both of the colleges have more or less the same placement stats. They don't have placement you dream of unlike JU and BESU. Most of the recruiting companies are IT companies. There are few companies for the core departments.
4. Board
KGEC is under the board of WBUT which is presently known as MAKAUT where JGEC in the other hand is AUTONOMOUS.

All branches are good, the word better is mere perception of an individual. For one Civil may be good for the other EEE and vice versa. I can tell you the current scenario which may be helpful in developing your perception. India is a developing nation with lots of infrastructure development, population growth and global warming in the years to come, there will always be a need for Structural Engineer, Transportation Engineer, Water Resource Engineer and Environment Engineer. And all these fall under the category of Civil Engineers. EEE stands for Electrical & Electronics Engineering. This branch of Engineering has recently gained momentum due to the industrial demands of having an individual with skill set of both an Electrical as well as an Electronics Engineer. But to clarify Electrical Engineering is the mother of all these branches (ECE, EEE, EI, CS IT). This branch may make you work in State Electricity Boards, make you a professor with suitable specialisation, make you do research and sell new technologies (thanks to booming renewable energy sector in the years to come) or make you shift to an IT field job if you loose interest during the course of four years easily. Satisfaction - It depends on personal thinking. But the life of civil engineer is spent mostly at construction site. This is obvious because after a structure gets built there is no work remaining for them. So be ready to work under sunlight, dust, helmet on your head, dealing with contractors, remote sites away from city. You will not get to enjoy day to day corporate life as experienced by IT people. On other hand, being a mechanical engineer you have lot of options to work in. Right from IT company to construction company to heavy machinery builders. So indirectly you have options to choose from. Now a days you must have seen mechanical engineers are becoming IT professionals as they just have to get there hands on programming skill and algorithm development. So think wisely and good luck.
