GATE 2020 – Graduate Aptitude Test in Engineering (GATE) is a national level PG Engineering entrance exam. It is conducted jointly by the Indian Institute of Science, Bangalore, and 7 Indian Institute of Technology (IITs). GATE 2020 will be conducted for a total of 24 subject papers, among which Statistics (ST) is the newest addition. It is expected to be held in the month of February 2020. The registration for the exam will open in the month of September 2019. Students who are planning to appear for GATE 2020 must check the GATE 2020 eligibility criteria. The score of GATE is also used by PSUs for junior engineer and other recruitment.

## GATE 2020 Syllabus

GATE 2020 Syllabus is a thing which every student must have with them. It is important because if they will have the syllabus with them, they will be able to prepare in a much better manner since they would have an idea as to how and what all topics they have to learn and prepare. Check the expected GATE 2020 Syllabus. It is likely to remain the same.
