GATE 2020 Cut off score is the minimum score that candidates need to secure in order to qualify the entrance test. Note that, GATE Cut Offs will be separate for qualifying the exam and for admissions. The admissions cut-off will vary for each participating institute as it is dependent on the number of seats available at a particular institute as well as the number of applicants therein.
Here we have tabulated the qualifying marks for the Life Sciences paper from the last three years. Candidates should bear this in mind that the Qualifying Cut-off will vary on the basis of the difficulty level of exam and the total number of applicants.
