Hey!

Cracking KVPY exam after preparing for a month is a tough task but not impossible. Cracking the exam relies on your abilities. Since not much time is left, do not go for very complex questions which you haven't been aquainted with before. Concentrate on the basics first of each subject. Take as many practice exams as possible. Examine the previous year's papers and practice similar sorts of problems again and again. Get to know the marking scheme as well. Practice the most repaeated kind of questions as you don't have time to go for the entire syllabus. Make sure you are clear with the basics.

All the best!
