Polity FOMO. Veterans please help!!!!

I have finished Lakshmikant thoroughly on my own. I also have Jatin sir's video lectures. I have watched few lectures and really liked his way of teaching. There's so much context and all. But lectures are around 130 hours and It's December already. Given almost entire junta will be soon going in prelims mode, will it be advisable to go through these lectures? Another problem is there's so much dictation within the lectures and it's time consuming. I am somewhat done with MH, Geography, Economy and my 1 paper in optional. Any help will be appreciated.
