Is rank under 20k possible from now?

I know aiims and Delhi colleges are impossible at this point but is a rank under 20k and state gmc seat still possible in 6 months🥺this is my last chance and I can’t afford to lose, I know I fucked up by starting this late but I’m willing to give the entire remaining time to neet only. I’ve only done 10 chapters in bio and 2 chapters each in chemistry and physics which I did in October.
