Dear Aspirant,

See doing NCERT would help you build up your basics well & good.But JEE Mains being a national level exam is highly competitive , so if one wants to achieve a good percentile and rank, then doing NCERT is not enough.

Reference books help to develop problem solving skills and get an idea of what level we have to prepare for .Also previous year papers are MUST , irrespective of preparation what you have done.
