GATE Qualifying Cut Off for Electronics (ECE) Paper

The GATE Cut Off is the minimum marks that GATE aspirants need to score to qualify GATE 2021/2022 exam. Candidates who score marks more than or equal to the GATE qualifying cutoff marks would become eligible to take admissions in M.Tech courses.

Most importantly, the GATE scorecard will be issued only to those candidates who score equal to or more than the qualifying GATE 2020 cutoff.

Candidates will be able to check the minimum scores required through the cut off of GATE exam below:

Candidates who have finished their engineering syllabus properly can easily crack the GATE 2021 examination.
