Candidates opting to appear in TWO subject papers must have a primary choice of paper, which will be their default choice and second choice of paper, which has to be chosen from the allowed combinations. Combinations other than the listed ones are NOT allowed. Under unforeseen circumstances, GATE 2021 committee has the rights to remove certain combinations at a later date. In such case, the fee paid towards the second paper will be refunded to the candidates.
