First, go through the whole syllabus of class 12th physics. 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.

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 practising.
- 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.

You can increase sitting gradually, it's not a one-day process. Take baby steps i.e. the first day sit for 2 hours and don’t involve yourself in these two hours anywhere except studies. Break these 2 hours into 4 slots. Each slot consists of 30 minutes. study with full focus in these 30 minutes and complete all the chunks likewise. Then second or third day increase an hour. This process will make you consistent and studies will become a habit. That’s how you can increase these hours as per your need and increase your sitting.
