Highly likely failing math tomorrow

Hey guys so backstory first ive been sick since 8th grade with cronic vomiting and i developed severe mental issues from that in 9th grade i broke my wrist and had 2 surgeries which resulted in me not being able to write for 1.5years, i became a really weak student then in 10th i somehow passed with 68% now in 12th my basics are really weak and i tried my best to study PCM (Phy and Chem went bad too) i think i am going to fail in all of them but i am keeping my hopes up so lets just say i am getting compartment in math. do you think the time from result-compartment is enough for me to pass math properly as a weak student (0 basics)?
