How tf do i manage SST at this point?

The whole year, ive studied consistently, but not EVERY subject. I studied Science at the start of the year bcz i liked it. I bought both aarambh and abhay and enjoyed the science lectures. I didnt focus much on math and sst, but when my preboard 1 result came, I had like 40/80 in math so i worked on it for like 7-8 days consistently like 5+ hours daily and now im in the range of 70-75 for preboard 2. i didnt focus on SST much, tho ive watched all the aarambh and abhay lectures and even prevoius year marathons. Now im scared of SST and how do i study it and make it so I can cover up all my past negligence. If theres a way to somehow cover it all CLEARLY in a day (ready to study like 12-14 hours), then please tell me. I tried reading a ch of NCERT but im not focused and dont understand. Please help me, how do i make SST strong and preferably in 1-2 days, so that i can start solving PYQs
