Hello

As you are asking for a study plan that will help you achieve your target in 40 days, I can help you with that, but your hard work and consistency matter a lot.

Also, you have not specified which exams you are preparing for. What is your target? So I am giving you a common plan that you can follow for any exam.

Make a clear timetable for 40 days and study at least 6–8 hours daily.
Divide your time between revision, practice questions, and mock tests.
First, revise important concepts and formulas from each subject.
Then solve previous year questions and practice papers regularly.
In the last 10 days, focus more on full mock tests and weak areas.
Avoid distractions and stay consistent every day.
Take short breaks, eat healthy, and sleep properly to stay focused.
