Hello Yashu,
As a rule of thumb, lateral admissions are given to Diploma holders directly in 2nd year of engineering. Normally, there is a table that gives qualifying branches of Diploma that are eligible for different branches of engineering. Unfortunately, every state has different rules. I would therefore suggest that you check it with webpage of DTE of Tech edu of your state for detailed information.
