I wont suggest u to follow wat Sahil did as I think he is either the exception who scored well in just 1 month of Study Or he was an xtrovant in IT (Topics like Flowchart is practice based) 4m earlier.
Rather I wud sugest u to first go through the sugested answers / scanner if u want more marx in less time then as u have still time in exams u can also go thru d Module so as 2 excel in the subject...specially for SM
Best wishes
