🎯 How to Study These Physics Chapters Effectively
Physics requires strategy, not just hard work. Follow these tips for maximum scoring:
✔ Clear concepts first
Learn the “why” before the “how”.
✔ Solve NCERT examples and in-text problems
Many NEET questions are similar to NCERT patterns.
✔ Practice numerical problems daily
Especially for Mechanics, Current Electricity, and EMI.
✔ Make formula sheets
Revise every morning and night.
✔ Use previous year NEET questions
This shows exact difficulty and question style.
✔ Take mock tests
This improves speed and accuracy under exam pressure.
✔ Revise regularly
Physics concepts fade quickly without revision.
🌱 Final Thoughts
Physics may seem difficult at first, but with the right strategy and focus on high-weightage chapters, it becomes manageable—and even scoring.
The chapters listed above contribute the majority of NEET Physics questions, making them essential for every aspirant.
