your percentile is best then go forward to jee advance

Hi Avinash!!! I would like to suggest you to brush up all the important topics once more as your concepts need to be crystal clear and then you can start solving JEE Advanced papers which can include papers from last 3-4 years, papers provided by different coaching institutes and so on and in any of those papers whereever you face a problem you should consult your book or guide and get it cleared as soon as possible.

Hope that helped.Thank you.
