Important Points to Note

NCERT Questions are Very important  3 Questions have come
straight from NCERT Book.

10 Questions are very similar to the questions in the NCERT Book
. Just values are changed

1 mark question has 10 Multiple Choice Questions, 5 Fill in the Blanks and 5 answering questions

In Answering questions, there is step marking. In MCQ and Fill in the blanks, no step marking

When cancelling square roots, don't forget to write
plusminus sign ±

Writing units is important or half marks is cut, eg: x =3 is wrong, x = 3 metre is right.

Formula of all chapters has 1/2 marks

Formula of Statistics (Chapter 14) has 1 mark

In Chapter 9 Heights and Distances, 1 mark is given for correct figure

1 Question of Theorem will come. (Of Chapter 6 or 10)

1 4Marks question of Construction will come

Remember the formula for Length of an arc (Chapter 12)
Length of arc = θ/360 × 2πr
It is used when length of arc is given, and we need to find angle

In questions where the answer can be found easily (like finding curved surface area of frustum if height and radius is given), calculation is difficult. 1 mark will be deducted if you have not found the exact answer
