If you believe in yourself and try hard all this week you can cover almost every part of JEE main syllabus. Give every subject a revision and try doing all previous year questions. This will help you more likely.

Consider chemistry an easy option here. Cover almost every chapter within 2 days, that can absolutely. If you want important chapters read the inorganic part properly from less chapters more questions come here.

Likely in physics and mathematics just solve previous year questions. Cover almost every important chapters. For more details visit,
