Whether you need to give an entrance exam for a Polytechnic in Automobile Engineering depends on the admission process of the college you choose. In Delhi, many polytechnic colleges offer admissions through CET Delhi (Common Entrance Test), which is a state-level exam for diploma courses. If you choose this route, you will need to appear for the exam, secure a good rank, and then participate in the counseling process to get a seat.
However, not all colleges require an entrance test. Many institutes, including Puran Murti Campus, also offer direct admission based on your Class 10 marks. This means you can apply directly, submit your documents, and get admission without appearing for any test if seats are available.
So the good thing is that you have two options—either through CET Delhi or through merit-based direct admission. This gives students flexibility. If you do not want to prepare for an entrance exam, you can still get admission easily, and if you want a more competitive route, you can choose CET.
