How to increase sitting to complete the Class 12 Chemistry Syllabus 2023-24?

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 to complete your Class 12 Chemistry Syllabus 2023-24.

Special Tips for CBSE Class 12 Syllabus 2023-24 for Chemistry

Pomodoro technique: You must have heard of studying for a short duration and taking a 5 minutes break. This method is called the Pomodoro technique. In this method, students have to study for 25 minutes. Then take a 5 minutes break to relax, and repeat the process. After being consistent for a week you can increase your focus span and also if you want to sit for a longer time then study for 50 mins and then take 10 mins break and you can repeat it 2 to 3 times. After that, take a long break of 20 to 30 min. This technique is very effective and you won’t feel tired and feel rejuvenated before every study session by using this method.

Feynman technique: This technique is a simple process where you first study a topic then you have to teach the same topic to another person. If you don’t have anyone to teach, you can pretend to teach it to an imaginary audience. While doing so, you will find where you are lacking and were confused about the topic. Read that topic again by book to clear the point where you were stuck. This technique is effective because you will understand the topic in-depth and also make it simple to teach your imaginary audience.
