Hello aspirant,
You are left with almost one year for JEE exam. In order to qualify for JEE Advanced you need to first clear JEE Mains entrance exam.

Preparation Tips for JEE Mains entrance exam:
**First go through JEE Mains syllabus and make a note of it.
**Go through previous years question papers for knowing the model of questions asked in the examination.
**First prepare the topics you feel easy, to boost up your confidence.
**Prepare your own short notes.
**Make flow chart of the concepts to remember them easily.
**After than go for tough subjects prepration.
**Regular revision is necessary after completion of every topic.
**After completion of the syllabus preparation then solve previous year's papers.
**Then go for sample papers solving.
**Take sample or practice tests/ mock tests/ online test series to check upto what mark you are with the concepts.
**Finally revise all the syllabus.
