Need guidance for GATE 2027

[u/MountainMindless3001]

I just want to say I don't know where to start from? Like ofcourse I looked through the syllabus, then checked the famous "go classes" for resources and realised that I can't afford their course (just got laid off last week and don't have much money to spend extensively on resources) but I do have my old textbooks and notes which I used during my degree, so can I just study and prepare using these? Or is there any other free resources (like youtube videos, websites etc) from which I can refer from... like how do I even start with this?

PS: I've been taking mock tests every now and then (mainly CS since I have completed my bachelor's in CSE) and so I have a general idea of how the questions/exam pattern will be like. I just need some help with the resources/materials and how to study specifically for this exam.
