Since quants was my weakest, I decided to focus on VARC and DILR. From getting 40-50 percentile initially, now I'm getting around 70-80-90 in these two sections. But I'm doomed in quants. I haven't attempted a single mock or sectional because I lack foundational knowledge in them. Any idea which YT channel or video would be the best to understand and learn basic easy concepts like arithmetics or number systems and atleast make sure i get 4-5 right on D-Day ?? Any help would be much appreciated

@Varun @Aspiring eagle, thank you so much. I'm gonna start with Raman one shots, his recent one which is 10 hours of continuous teaching, thats some serious dedication from his side.

Raman Tiwari also explains Quants well in his one-shot videos. Questions prepared by him test the effectiveness and efficiency of candidates. Otherwise, you will fear to cover basic topics when confront with 4-5 parts videos 2 hours long each.

Second best recommendation would be Cracku and Rodha.

You should check out Cracku's QUANT revision videos. You will go through all topics in those videos.
