Hi Runjhun this is Jakka Vamsi Krishna

Absolutely yes, DRDO accepts either last year's GATE score or present years GATE score. GATE score plays a crucial role in the final selection.

Graduate Aptitude Test in Engineering is one of the toughest exams in India. Once if you qualified in GATE it is valued for 2-3 years. You can apply to your post-graduation and apply for DRDO or you can directly apply for DRDO with your graduation degree.

But, in the first case, you can have high chances to be selected for the job because you hold a Masters certificate and have a wide knowledge.

Remember the main thing that GATE score only reserves 80% of weight and the remaining weight is a personal interview.

ALL THE BEST

Hello Runjhun

Each and every Psu's accepts GATE score but the case and the main problem is that unlike IIT's which accept's a GATE score of maximum 3 year's old, Psu's only accept the current GATE score only.

So, for applying in any PSU's you will have to use GATE 2019 score only ( if it is valid )
