How to complete the CBSE Class 12 Physics Syllabus 2023-24?
Students must go through the entire CBSE Class 12 Physics Syllabus 2023-24 and sort the chapters based on the difficulty level. Prepare a monthly plan and divide the units according to that plan. For example- you can choose a unit according to your convenience. Complete the first reading of a chapter from the chosen unit. If you find any difficulty in any topic then take help to your teacher or you can search that topic on the internet. Likewise, complete all the chapters and revise them periodically. That’s how you can retain all the units for a longer duration by multiple revisions. Repeat this process for all the units.
How to Develop Interest in Class 12 Physics?
Most of the students find physics difficult. They failed to solve numerical problems and failed to remember derivations. Here are some tips listed below follow them and make physics interesting.
- Start with basics, yes you have heard it right. If you want to understand what is the gravitational force, first learn what is force.
- Imagine and relate concepts with your daily life.
- Understand derivation step by step, don’t mug up.
- Start with easy numerical then gradually increase their level. If it is not working for you then thoroughly read the topic of that numerical and start practicing.
- Last but not least, physics is all about concepts don’t try to mug up them, try to understand them. Practice questions as much as you can it will boost your confidence.
