Not a legal or short term advice, but rather a long term one in place of doing part time jobs and prepping for gate and attempting again after 2 years.
Once you start your job start prepping for interviews, do leetcode as much as you can and start applying to some nice product based companies. Your career will progress much better than doing GATE after 2 years.
The decision you are making is a courageous one but seems like a necessary one, godspeed to you
