Hello Anurag,
Start practicing all the basics for Physics, Chemistry and Mathematics. You may consider joining a coaching institute as the competition is huge and harsh.
One mark can lead to a large difference in the final IIT JEE rank, therefore you need to be versed with all the basics.
Be devoted, dedicated and determined. Have a clear goal and be proactive rather than reactive. Take notes while you study. Do not panic when a new method of solving questions or a new approach is introduced. Always review what you have studied in the past few days. Keep a day in a week to test yourself. Always ask your teacher when you cannot understand a certain topic. Do not hesitate or feel shy. Avoid distractions such as mobile phones, futile internet searches and so on.Be thorough with all topics. A superficial understanding of any topic will not help in IIT JEE. If you are comfortable with group studies, go for it. Keep a track of your strengths and weaknesses.
All the best!
