Need guidance

Hey everyone, I'm currently in my 3rd year of engineering and I'm planning to attempt SSC CGL next year. I’m honestly not sure if it’s the right decision, so I wanted some guidance from people who’ve been through this. I don’t really see myself writing code my whole life, and engineering has been feeling pretty exhausting lately. That’s one of the reasons I’m considering government jobs, and SSC seems like a good option to me. I think I’m fairly good at maths and aptitude (at least that’s what I feel), but I have zero idea about how things work in SSC prep the pattern, timeline, resources, or what level of competition to expect.

So my questions are: Is it a good decision to start preparing for SSC CGL in my 3rd year?

What things should I keep in mind before starting?

What resources or courses (free or paid) are actually worth it?

Any advice from people who cracked it or are currently preparing?
