Yes, you can definitely enter B.Tech later through lateral entry if you want to upgrade your qualification after completing a diploma from the Polytechnic in Mechanical Engineering College in Delhi NCR. This is a common and well-recognized pathway for diploma students who wish to continue their studies and earn a bachelor’s degree in engineering.
After completing your three-year diploma in Mechanical Engineering, you become eligible to join the second year of a B.Tech program directly through the lateral entry system. This means you save one academic year compared to regular students who enter B.Tech after Class 12. It is an excellent way to upgrade your qualification without starting from the beginning.
Many reputed universities and engineering colleges across Delhi NCR and India accept diploma holders into their B.Tech programs. The process usually involves appearing for a lateral entry entrance exam (like LEET or state-level tests), after which you can secure admission into the second year of B.Tech. Some private universities also provide direct admissions based on merit in the diploma.
By choosing this path, you will have a chance to deepen your technical knowledge, specialize in advanced areas of mechanical engineering, and also open doors to better job opportunities. A B.Tech degree also allows you to pursue postgraduate studies like M.Tech, MBA, or even prepare for government exams where a bachelor’s degree is required.
The diploma gives you a strong foundation with practical skills, while B.Tech adds more theoretical and advanced concepts. This combination makes you highly employable in industries like automobile, aerospace, thermal power, robotics, and manufacturing, as well as in government PSUs.
