Hello friends

Just read all those stuff and try to remind it and if you have doubts in any of them then go through the book

It's beneficial:

1)real number: for finding HCF and LCM by prime factorisation.

Euclid Emma and terminating or non-terminating condition...

2) polynomials: relations between roots and coefficients of equations ( quadratic and cubic both). How to write quadratic equations whose roots r given...

3) linear equations of two variables:

A condition of no solutions, infinity solutions, and unique solution,

Method to solve linear equations ( eliminating, cross, and substitutions)

4) coordinate geometry: section formula, the area of triangle formula and how to find ratio when coordinate is given

5) quadratic equations: completing square method, nature or roots,

6) Ap: nth term formula and summation formula

7) circle: theorem: ( tangent from an external point are equal)

8) Area related to circle: area of the sector and triangle area ( 1/2 r^2sin(Thota half angle)

9) construction: how to draw triangle when required is ( 3/4 type 5/3 type), how to draw a tangent from the external point.

10). Surface area and volume: all formula including frustum

11) : trigonometry: complimentary angle formula, and identity

12) application of trigonometry: tan60: root 3 and tan30: 1/root3

13) probability: formula

14) statistics: all formula for the mean( shortcut, assumed mean, and step deviations,), mode and median formula, and the relationship between them.. how to draw more than and less than ogive.

15) triangle: all theorem of this chapter (BPT, PYTHAGORAS theorem, and questions based on that, area of similar triangle related to side ) last exercise of NCERT last 7questions

These all topics are the important one ...

I hope this will be helpfull for you guys.
