Hello Kuldip,
Lateral admission in 2nd year of engineering are invariably restricted to students of the state who have passed diploma. Some states conduct entrance exam while some states give admission based on marks obtained in diploma.

It depends upon university college strength and left seats. It also varies from state to state. So don't worry more about the seat, perform well in your qualifying exam and then appear in the exam and you will get the seats.
All the best!

Hi,
Admission is through counseling based on the rank obtained in West Bengal Joint Entrance Lateral Entry Test (JELET).

Yes, you can take lateral entry in 2nd year, but it is more beneficial when all the subjects are same as in your present college. There might be a problem of adjusting with a new college and surroundings. The change can either be positive of negative. It is completely up to you as to how you manage the transition. There sure are lateral admissions but for the process you need to contact the management.
