To create a practical study plan for an 11th standard student, you should plan your study according to your style if you are going to follow anyone it might not work as it is not necessary if the plan works for someone it will work for you too.

So start from analysing your syllabus, identify your strengths and weaknesses, set realistic goals, allocate time for each subject based on their importance, incorporate regular revision sessions, and schedule breaks to maintain focus while considering your individual learning style and daily routine.

Revise timely to remember what you learn, review the plan if its working properly and the final thing keep calm and relax.
