Law school or constant battle with imposter syndrome?

I'm a law student in Ernakulam (3 year LLB), I took law cause it genuinely seemed fun but now I feel lost. I feel like I'm pretending to fit in. In class everyone's answering random case laws in unison, and I'm sitting there hearing it for the first time. It seems like everyone belongs here, and I'm just pretending to belong? Is it just me? I often feel this way when I chair MUNs too, it feels like I'm just pretending to know things. Sometimes I fumble my speeches, sometimes I'm excellent at it. I just need to know if there's anyway I can overcome this feeling of being an imposter.
