How do I join Thapar University?

You can enroll at Thapar University through a JEE Main rank. Besides, there are 3 cut-off lists released and 2 separate spot rounds, depending upon the availability of seats. You are required to fill the registration form, as per requirements. This is solely for the B.Tech branch. 

You can also secure admission at Thapar University even if you are pursuing any B.Tech course from any other university. You will have to appear for the 1st year December Test. The syllabus is very closely related to JEE Main. However, the exam level is quite low. 

In case you are an MCA aspirant, then you can directly go on to take the MCA entrance exam conducted by Thapar University. My cousin, after he secured the rank 96, could not acquire admission because the seats of the university typically got filled until the 46th rank. 

To add more, you are required to take the AIEEE exam for securing an engineering seat, while a direct entrance exam for MCA. Hope this helps answer your question, wish you all the best!
