First of all u have to study the basic equations of motion
v=u+at
S=ut+1/2at^2
V^2=u^2+2as
i think you already done that
So you dont worry about your xam
Only concentrate the concepts only
If u get a problem then read it carefully and try to understand what we want to find and how
So try to understand the question by reading the questions more time
And try to get the concept
If u get the concept then u have the equations u can apply it
So most important think is try to get the concept by reading the questions
Pls try this from your home
take a question and try to solve it like this
If u get what i said then i sure that u will definitely get good marks in your exam
All the best
