I have 44k rank in DTU LEET and 74% in 12th. Can I get a seat in DTU?

No, you are not eligible for the DTU LEET (Lateral Entry Entrance Test) if you are currently pursuing B.Tech in Biotechnology from NSUT

Offcourse you are eligible my friend to write exam if you secured a minimum percentage or marks according to DTU Tgen your eligible for that college 

In the DTU LEET (Delhi Technological University Lateral Entry Entrance Test) for CSE (Computer Science Engineering), Physics and Chemistry are typically not included for Diploma students. The subjects generally covered in the exam for lateral entry students are:

1. Mathematics
2. Engineering Mechanics
3. Computer Science & Engineering Basics (such as Data Structures, Programming Languages)
4. Basic Electrical Engineering

The focus is more on technical subjects related to the engineering discipline, especially computer science, rather than basic sciences like Physics and Chemistry.

Approximately 45 to 60 seats are available for B.Tech in mechanical engineering through LEET. Candidates must know that the number differs in each institute and this is an average estimate.
