so i have my exam in 4 days and havent studied a single chapter the entire year. and everyone says its impossible to solve slightly complex numericals as to do that it would require me practicing 1000+ questions[which i obv can do now] so would the theory part be enough? formats? formulas? someone help please. how can i get decent marks now and im talking like 50/80 and ik this is sub is for people in their 20s but please help me i need advice
