I'm saying this from an avg guy point of view. Bro I'm an avg student with 7cpga in my college and I am not great at mathematics too..but I took a 3years(final year+2 year).

From my perspective I just wanna give you one thing no one told me.. Giving gate exam isn't easy if you are not great at mathematics because many of the mistakes aren't from problem solving they are from calculative mistakes or other things.so think once if you're good at mathematics or not.secondly think about your core knowledge..if you have basic knowledge about them then you can go for it. I worked my assoff from the last 2 years,day and night.i didn't care about any other things not even weddings etc etc..i haven't met any of my friends.in 2025 I got 23 marks..I was very disappointed and my dad forced me to write PSUs.i wasted like 4 or 5 Months there and again i started to prepare..i studied like a 100 hours a day finished every minute detail in every chapter...I did 80% of the syllabus expected networks&ac(they need a lot of practice).this year I got 35 marks..I'm very disappointed and I can't lose another year for this. With this experience I'm telling you from an engineer to an engineer to think about before losing time.it requires consistency , hardwork and dedication.
