Dear Aditya Popli,
There are many good colleges in Punjab who provides lateral entry in B.Tech. But I would suggest you to choose either Lovely Professional University or CGC Landran Mohali. These two are good colleges and provide good placements.

Hello Sai,
Lateral admissions are prerogative of concerned state govt. Normally table is published indicating which branches in diploma will make you eligible for which branch in engineering. Check for PI with your polytechnic where you completed your diploma & they will inform you immediately.

You are eligible to seek admission in B.Tech lateral entry in the 2nd-year of mechanical engineering after Diploma in metallurgy. You may appear for LEET exam conducted by various engineering colleges or state governments.
