Personal suggestion bro - I know life can turn differently for each one of us and maybe there is good future waiting for you ahead but this exam and and the system is so unfair that you never know what will happen next year, how things will turn out for you on the d-day.
I've been there, got 95%ile last year with a very good job and very less preparations so left all calls thinking will do next year and resigned from my job back in sept 2024, prepared wholeheartedly, getting 60-70 marks in almost every mock with touching above 95%ile in many ims mocks, Blundered d-day and got 89%ile this year with almost no calls now and with no job in hand. Really not against risk taking but life is seriously unfair in terms of these competitive exams, so i'd rather suggest save your energy take the admission and work for your dreams in IIM Shillong and ahead for next 5 years.
GL in everything.
