sir should i take drop or continue to study for 2nd attempt jee mains .As i my expected score is 150 or above of it but not less.

Dear aspirant,

Please continue preparing for the JEE examination. 150+ marks will fetch you a seat in one of the NITs in the last rounds (this is for general category). You will most probably be eligible to write JEE Advanced as well. Taking a drop is an extremely risky decision to make and it should only be made in cases where you think you could improve your performance by large folds in the coming year. So, please think well before making that decision. Also, focus on memory-based topics like inorganic chemistry, statistics, environmental chemistry to boost your marks further. Hope this helps.
