IIT JEE is the one of the top exams conducted in India for the admission in the engineering courses of the 15 IITs, Indian School of Mines and IT BHU which has been converted into an IIT and named as IIT BHU. IITs are golden dreams of several students in their life, but is achieved by only those students who do the smart work along with their hard work. One should go thoroughly through the available sample papers of JEE to get the idea about the types of questions which has been asked time to time. So, to ease your work, Here is the Physics Sample Paper for JEE Exam which will assist you with your Physics problems.
