Hey,

If we talk about government colleges offering Computer Science Engineering, then, the admission is mostly based on JEE Mains/JEE Advanced entrance exams. Then, a centralized counselling process is organized either by different state statutory bodies or National statutory bodies. The application dates may vary under which counselling process you want to exactly apply. However, you can get the important dates for JEE Mains counselling and other details over here: https://engineering.careers360.com/articles/jee-main-counselling

You need to note that some states organize their own state level entrance exam for admission into the B.Tech CSE course and the counselling schedule will vary highly so does the application dates. You can better mention the state or exam in which you are focusing for admission into B.TECH CSE. Generally, for government colleges, entrance exams score is only accepted.

Some of the top B.Tech CSE Institutes includes:

• IIT Bombay
• College of Engineering, Pune
• IIT Madras
• MSU Baroda
• Delhi Technological University
• Jamia Milia Islamia, New Delhi
• LD College of Engineering, Ahmedabad
• IIEST Shibpur
• IIT Delhi
