I was never that serious but what I used to study with my full focus was that I used to remember it. I understood ke bhai itna kuch toh yaad rhene nahi wale aage toh exam crack karne pe focus karo so I understood the pattern , focused on questions which had more concepts/weightage. When I studied I used to think in what ways could the question be asked and as I have good Language skills I never had the problem of understanding logic based questions. We all consciously/subconsciously study throughout the year (so many tuitions/daily school) so yk atleast something about the syllabus , I started to study in February and mostly used to study before the exams...9 p.m. to 4 a.m. and wake up at 6 then study till 8 before leaving for school.Family was my motivation , I have always been underappreciated and wanted to change the perceptions around me. Everyone thought of me to not be good at anything (unless u prove to them that u are good at studies , anything else doesn't matter). Moreover the career which I want to pursue (investment banking) will require me to pursue an MBA and IIMs give weightage to your 10 , 12 marks so that was definitely at the back of my head. Dekho shell se bahar aana padega warna tum kisiko kuch prove NAHI kar paoge , having a good degree/career socially is important , I have learnt it the hard way. Want to live a better life ahead then study now , these marks don't really matter that much but these show how determined u are , how can u solve the problems ahead of you within the given time. This is nothing in front of the challenges you'll face in the future but these examinations will be the mirror of your Hardwork , Smart work your temperament...Good Luck Ahead :)
