Should I ditch calculus? class 12th maths

Maine non calculus wale sare chapters kar rakhe hain but meri abhi theory hi hui hai aur bahut limited questions kiye hain. Continuity differentiability and aod bhi thodi aati hai. Probability, vector 3d ke questions bhi nahi kiye abhi. Should I ditch the rest of the calculus kyuki wo scratch se padhna padega, and try and do maximum question practice on the chapters that I have completed till now? As of right now mujhe sirf pass hona hai aur extra marks are always appreciated ofc. Aaj bhi all nighter pull karna padega probably.
