How can I make my 11th physics strong in 1 month time?(if physics is my one of the weakest subject in 11th class among all other subjects).

firstly if you have anything in your mind that is bothering you or making u disturbed you need to take a step away from it to gain complete and happy concentration and you'll be motivated automatically.

Please keep on reffering more books(refer h c verma) and e-learning is very essential for eg. if u have a doubt refer through internet coz internet makes many things and gear up from your base level (from grade 6 books),indepth conceptual learing is important in learning physics thats it enjoy physics!!!!

• You should follow a proper timetable and give some more time to physics than other subjects.
• Don't waste your time on social media.
• Start with your Ncert book and read it's concepts and use it to apply in the questions.
• Make formulas list and try to practice numericals problems from ncert book as much as you can.
• Make proper notes and revise it at the time of exam.
• Write and practice conceptual problems and numericals.
• Find out the techniques/methods through which a specific problem can be solved.
• Analyse your preparation everyday and try to get better and better.
• Don't loose your confidence and be motivated and calm.
• Refer to previous years questions of class 11th and solve it .By this you will get an idea of how the questions are asked in exam.
