Maths- Since , not enough time is left, just do ncert thoroughly and properly , if you can't complete the syllabus, just focus on remembering the formula, solving examples is the best way to check yourself, ask for important questions from your subject teacher and just do them along with the examples. If you are left with time try solving the miscellaneous exercise because it is the most important exam to score good marks.

physical education- it is very easy as a subject, just read the important headings and you will be able to frame the answers yourself. A thorough reading of the chapter is needed, learn the headings and you will be able to score really good marks.

business studies- the same way, here too you need to read the chapter and learn the headings, clear the concept and try to solve the MCQ as well because they will be a way to score good marks.

remember, not to consider yourself as an average student, just trust your hardwork, nothing is difficult, stay focused and give your best.

Hello Pratham

At this point, what lies in your hands is to revise what you have already studied and face the question paper with a calm mind. Try practicing mock test papers from https://www.google.com/url?sa=t&source=web&rct=j&url=https://school.careers360.com/articles/cbse-class-12-sample-papers/amp&ved=2ahUKEwiwqe_foMz0AhWJad4KHRE1BJYQFnoECB4QAQ&usg=AOvVaw3wGUzUiq2WDlOZRtkIPmaR you can also study a few new topics if you want. But don't stress yourself out and don't panic because then you won't be able to give your best. Take rest and occasional breaks. You will clear your exams with flying colors. All the best. Hope that helped
