Hello aspirant.

Believe in yourself. you can certainly improve in mathematics. Mathematics is not tough. It is totally full of logic. If you can track the logic, you will become a master in mathematics.

• Fast Track Objective Arithmetic : Rajesh Verma/ Arihant Publications; (
• Quantitative Aptitude for All Competitive Examinations : Abhijit Guha/ McGraw Hill Education; etc.

You can pick one of the books and practice daily.
