I would suggest you to regularly check the official website of KIET Ghaziabad for updates regarding admission dates. KIET generally releases the admission dates around the time of JEE-Mains and the start of the academic year. Students have to apply online through the institute website.
For the current academic year, admissions will be done on the basis of JEE-Main scores. The JEE-Main registration date started on November 30, 2023. After that JEE-Mains 2024 exam was held on January 24 - February 1, 2024. The 2nd session was held on April 1- April 15, 2024. The tentative dates for UPTAC registration and counselling for admission to BTech are around July, 2024 - October, 24.
