How to practise Dual Nature of Matter and Radiation PYQs

1. Start with the concepts at the top of the table. They have come back the most.
2. Solve one year’s Dual Nature of Matter and Radiation questions from the official PDF against the clock, then check the answer listed below.
3. Log every miss as a concept gap, a calculation slip or a misread. Each needs a different fix.
4. Once a concept is clean in two papers, move to the next. Then sit a full paper from the year pages.
