Observations from the paper

Some 1 mark questions have 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

NCERT Questions are very important  3 Questions out of 30 have come straight from NCERT. Other questions is very similar

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

It is important to Revise the topics from
Concept wise
. Just check the theory, and the questions in order they are given
 Make sure you have 2 pencils, 1 compass, scale, eraser, sharpener with you in the geometry box

Make sure you do atleast this year's sample paper.
