I have only one week left for my 12th boards, how should I prepare for the exams?

Study only those portion which u have already studied.

And for remaining portion u can do only ncert.

For maths

• examples are most important .

And one six marks question from integration ( last exercise after the question ni. 24 ).

• Practice for determinants and matrix method.
• Also pay time for 6 marks question’s chapters
• Study only from ncert for board. u vil easily get around 80 to 90
