Electrostatics is a scoring chapter if your concepts are clear. Many direct formula-based questions are asked from this unit.

2. Current Electricity

• Ohm’s law

• Resistance and resistivity

• Kirchhoff’s laws

• Wheatstone bridge

• Electrical power

Numerical questions are common from this chapter. Practice circuit-based problems carefully.

3. Magnetic Effects of Current & Magnetism

• Biot-Savart law

• Ampere’s circuital law

• Force on moving charge

• Moving coil galvanometer

This chapter tests both theory and application-based concepts.

4. Electromagnetic Induction & Alternating Current

• Faraday’s laws of induction

• Lenz’s law

• Self and mutual induction

• AC circuits and reactance

Many students find AC numericals tricky, so practice regularly.

5. Optics

• Ray optics (reflection and refraction)

• Mirrors and lenses

• Optical instruments

• Wave optics (interference and diffraction)

Optics is one of the most important and frequently asked units in CUET Physics.

6. Modern Physics

• Photoelectric effect

• Bohr’s atomic model

• Radioactivity

• Semiconductor devices

Modern Physics is usually easy and scoring because questions are direct and theory-based.

Preparation Tips for Physics

• Practice numericals daily.

• Revise formulas every week.

• Solve NCERT examples and exercise questions.

• Attempt CUET mock tests regularly to improve speed and accuracy.

Smart Strategy to Score High in CUET Science

1. Follow NCERT Strictly

Most CUET questions are directly based on NCERT. Avoid too many reference books.

2. Practice Mock Tests

Mock tests improve time management and help you understand exam patterns.

3. Focus on Accuracy

Since negative marking may apply, avoid random guessing.

4. Make Short Notes

Prepare formula sheets and reaction charts for quick revision.

5. Manage Time Wisely

Attempt easy questions first and leave lengthy numericals for later.

6. Revise Regularly

Daily revision helps in long-term memory retention.
