I am really confused b/c am unable to understand that how to deal with this subject.The biggest hurdle in my way is that my cramming is so weak. In my whole career i never did this practice i just read the topic 2,3 which develops a concept and on the day of paper i jot it down whatever i have in my mind but this formula is not working here even though i read a topic multiple time but at the end of the day when i try to recall things i find my self blank. what to do.
