Engineering Admission Process

Dear Preetham,
The best universities for doing B.Tech in automobile engineering through lateral entry are Delhi College of Engineering, Maharaja Agrasen-Delhi (affiliated from IP University), LPU-Punjab, Chandigarh University, Graphic Era University-Dehradun, DIT-Dehradun and College of Technology-Pantnagar.

LEET is a state wise examination. You may confirm for which state and university are you seeking information. You may re-frame question and raise it again for an expert to answer.

You may please confirm for which university are you seeking information on lateral entry admission.

Anna University is a better option for lateral entry admission in B.Tech ECE because of university's all India ranking and brand image.

Dear,
There is no disadvantage of pursuing B.Tech in a particular branch in the 2nd year because from the 2nd year only the particular specialisation study will start and in next 3 years you would obtain, skills, knowledge, internship, project work and mainly you will get the same B.Tech degree as awarded to the student who took admission in the first year.
All the best.

There are very few study centers under IGNOU offers lateral entry for BCA. For detailed information, you can check out the official link below:

No, good BBA institutes have their own admission procedure. You can't find any institute that gives direct entry into BBA programme like B.Tech. You have to complete 12th and then seek admission.
