Hello,

KVPY SA exam will have single paper with objective-type multiple-choice questions (MCQs). Duration of the paper is 3 hours

These are some tips which can help him to remain focused and score well-

NCERT books are best books for KVPY preparation. To win the scholarship, it is wise to be vigilant and find ways to be better than thier peers. Solve as many KVPY past year papers and sample papers as he can, and analyze his performance by comparing it with the given solutions. With a month or two of focus and practice, he should be able to score well in his KVPY scholarship exam.do remember to follow a timetable made by him own according to his weak and strong concepts. 

Hope this helped.
