Lateral entry

There is no way to get direct admission in DTU B.Tech lateral entry program.
You have to appear for LEET exam to get admission in DTU.

Around 45-50 marks.

If you are a diploma student you can join directly in the 2nd-year. Then there is no chance for lateral entry because they cant provide certificates for you.

The lateral entry is for those who have done diploma instead of their high school. They are directly admitted to the 2nd year of the engineering instead of going to 1st year.

You may go to http://www.rtu.ac.in/RTU/reap for more information.
You can choose some best colleges in Rajasthan. One of them is Anand ICE, SKIT & JECRC-Jaipur, it provides better education with latest labs, best faculties, global exposure, good placements.

I think you should go in Kanpur institute of technology. It's a very good college in terms of the facility and quality of education that it provides to the students. HBTU can also be other option.

Hello Jahid,
Yes, you can get lateral admission in 2nd year of aeronautical engineering after completion of Diploma in mechanical engineering provided you fulfill other criteria if required. However, admissions are only in colleges of your state.
