hello 

Azhar amin

acoording to my knowledage the MTG is good for upto the JEE mains exams it is not upto the mark for the JEE advance My better suggestion for JEE advance as well as the JEE Mains plz take the look on the pearson in which the excellent content in the physics problems sloving and also it is good for maths and chemistry 

thank u
