Dear Monu,
To score good marks in Maths you can go through NCERT books to clear your concepts and after completing your NCERT you can go for RD sharma.
You can refer previous year papers to understand the level of the exam.
Practice is a key to score good marks in your exam so you can solve as much as MCQs and mock test series for your practice.
All the Best!!
