Hey there!
When I was in class 10, that is two years ago, R.D Sharma was considered to be the Pioneer of Mathematics. So what i suggest is, finish ncert book as soon as you can, and switch to R.D Sharma! Once you’ve finished with it, you can practice some question papers to gain confidence and time management! And don’t forget to Practice unsolved Exam idea Sample papers! Hope this helps! Comment for further queries!
