Dear Kanade,

 Understand the basics of everything that you study very thoroughly. If your roots are strong you will be able to understand the concept of anything that comes out from it. Once you understand, you should be able to explain and express in concise terms anything on the subject on paper or words or by actions. This will show you the way to become a topper in your diploma or Polytechnic.

Hope I have made myself clear.

Best Wishes!
