Hello dear

I would suggest some tech niques follow if u like.

Be good at tables up 25,be fast in addition ,subtraction, multiplication ,divison .don't be silly about these.(how about SMALL STONESin your kidney not silly right)

learn 1 to 50,cubes and squres

In your free time put randome big numbers on paper and try to caluclate them and check with your calsi when u done

While your walking out you come across cars ,and bikes with number plate suppose for example : AP21 1331 tri to figure out what is 1331 ? It is odd number ,11 cube like that.

be good in all topics you know like concept

Don't depend on formulas when u clearly know the concept u can do with out formula . I did it worked

Don't listen to number of videos you might confuse

try to slove abundant number of problems on every topic so you may come across many models

Suppose u like tricks (videos) , listen to them and apply them every time

Instead of doing Random aptitude questions set a period for one topic like for time and distance for one week ( at least 400 problems) . PDF also available

Mainly patience u may come across difficult calculations ,but u have to do it

Fractions are main problem for doing maths so practice well

Hope it helps
