Sir i just appearing in 9th standard and i want to start my jee preprtn so could you guide , about which dlp will be best for me...

dear student 
from class 9^th , donot take stress on jee preparation , just be through with ncert and normal ref books of s chand , and r d sharma for maths . 
and if u want dlp then take trishna foundation courses , they are awesome . 
alongwith that , start reading mtg magazines , they will boost your science knowledge . 
and donot take much stress from class 9^th , else you will not able to run properly in the JEE race from class 11^th . 

hope it clears 
regards 
kindly approve
