Last-minute Obsession with Relevant Evidence Under Section 3 of Indian Evidence Act

Yaaar, I'm freaking out, guys! Tomorrow's the day, only 3 days to go, and I still haven't grasped Section 3 of the Indian Evidence Act. Relevant, irrelevant, it all seems to be going round in a blur in my head. I've read it so many times, but it's like the rules of relevancy are taunting me, telling me I'm never going to remember them. What's relevant, what's not, is there a specific rule, or are they all connected? I've been studying for weeks, but it's this one thing that's eating into my confidence. Has anyone else struggled with this? Any tips or advice, yaar? What's your strategy for making it stick? I'm seriously worried I'll get it wrong in the exam and that'll mean losing precious marks. Help, anyone?
