Hello there!

Greetings!

I am extremely sorry to tell you dear but I didn't get your question,  also you haven't mentioned which hindi exam are you talking about,  if you are asking about scoring good marks in hindi exam in your board exam then it's not that tough , you just need to go through all the poems and storues which are in your syllabus and focus more on grammar section and then you should focus on writing section like letter and article writing,  you should solve at least 5 sample papers before your exam and then you will be ready to ace your hindi exam.

Thankyou
