I have been lazy these days and i have all the notes and stuff ready. I have like 10-20 days till my trials. Is it possible to cram ALL OF PHYSICS AND CHEMISTRY and learn it in depth to an extent where i can shred the entire test into pieces ie 100%. Additionally, i have an extremely solid understanding of both physics and chemistry, its just the small details i need to revise like lead acid battery cell advantages, disadvantages, reaction equation etc.
