Yes, most Coimbatore colleges, including PSG Tech, Karunya, and Kumaraguru, primarily admit students through TNEA counselling, which is based on Class 12 merit rather than JEE Main. JEE Main is mainly relevant if you're targeting government institutes like NITs. So a strong Class 12 score alone can

No, I don't think you can get into B.Tech EEE at Ajay Kumar Garg Engineering College, Ghaziabad with JEE Main rank of 5,30,000 as General, non-UP domicile candidate. Typically, closing rank for EEE close much earlier around 3,00,00.

No, JEE Main is not mandatory for BTech admission to SVSU Meerut. While JEE Main scores are accepted for BTech application, students can qualify directly through the university's SNET examination or Class 12 merit.

No, JEE Main has not been mentioned as an accepted entrance exam for BTech at GLA University.

Candidates who want to apply for BTech at this institute must appear in their own entrance exam called GLAET. 

Admissions are based solely on scores obtained in this exam along with performance in PI rounds.
