Hello student,

You have a lot of time to prepare for jee mains and jee advanced 2020.Since you will be giving jee in 2025, as per calculation you must be studying 8th class.So this is the right time to get command over even small topics in difficult subjects like maths and physics.More than maths, please concentrate more on physics as physics will be difficult for both jee and neet and both the examinations have negative marks as per 2020 pattern.Keep learning concepts , understand them and don't leave any topic unattended.Students who are strong in foundations in the subject have greater chances of scoring really well in jee or neet.
