Hello maghna Rai
  
There is no extra syllabus other than your intermediate (+2) syllabus. The entrance test is JEE mains which is of 360 marks (physics-120, chemistry-120, mathematics-120). 80-85 % of questions are from NCERT text book syllabus only. And some other questions are from advanced topics.
