About this test

This Science (विज्ञान) mock test is a mixed revision paper for Class 10 students who want to practise Physics, Chemistry and Biology together, the way the board exam does. It includes questions from Electric Circuits (विद्युत परिपथ), Refraction and Power of a Lens (अपवर्तन और लेंस की क्षमता), Reactions of Acids and Metals (अम्ल और धातुओं की अभिक्रियाएँ), the Human Heart (मानव हृदय), and Evolution and Sex Determination (विकास और लिंग निर्धारण). Solve it in one sitting with a timer, without looking at your book. Afterwards, check each answer carefully and note the topics where you lost marks. Regular practice like this builds speed and confidence for school tests and the board exam (बोर्ड परीक्षा).
