GATE 2020: Syllabus for Computer Science and Important Dates

PUBLISH DATE 17th October 2019

Indian Institute of Technology (IIT) Delhi will conduct Graduate Aptitude Test in Engineering (GATE) 2020 in February 2020. GATE 2020 would be a Computer Based Test (CBT) which is scheduled to be held in various cities across India and six cities abroad.

IIT Delhi commenced the registration process for GATE 2020 examination on September 3 and ended on October 5, 2019. According to the tentative schedule available on the official website, GATE 2020 result would be declared on March 16, 2019.

IIT Delhi has released the syllabus for GATE 2020 on the official website. Candidates are advised to learn and understand the syllabus thoroughly to make your exam preparation easy-peasy.Computer Science and Information Technology syllabus for GATE 2020
