Hello Aspirant,

In CLAT exam , the math section questions will be asked at an elementary level .  And the syllabus for Elementary Mathematics is mainly based on the fundamental concept of Mathematics such as Number system, Decimals and Fractions, Interest Calculation & Discounts, Approximation, Logarithm, Average, Roots, Surds and Indices, HCF and LCM, Ratio and proportion, Profit and Loss, Areas and Volumes etc . So if you are good with all the math concepts upto class 10 , then you will ca handle the section easily. But of course practice is veey important to get the speed and accuracy so solve a lot of mock tests and do topic wise problem solving on  daily basis.

Quantitative Aptitude for Competitive Examinations by R. S. Aggarwal and Magical Book On Quicker Maths by Tyra are good books for preparation .
