Hi Divya

KVPY and JEE are meant for testing 2 very different things. KVPY tests the candidate's research aptitude and skills, while JEE tests the ability of candidiate to apply concepts to engineering and close to real world problems. Solving KVPY papers would not be very helpful. The exam pattern for the 2 is also very different. Even though the syllabus might be same, you will realise that you need an in depth knowledge to solve KVPY papers.
