Centralized Admission Committee or CENTAC had released the application form for 2019 in May 15. The application fee is 1000 Rs for General category and 500Rs for Reserved Category. It might have closed down on 30th of May. CENTAC apllication form for NEET however had been released on 6th of June. So the application window for Btech is already over but it is still open to Medical aspirants who appeared for NEET. Hope this answer helps.
