Grammar itna mushkil kyon hota hain ?

I always lose marks in it

really u know why coz u dont study

 I make a mistake between ka and ki always . How to rectify it ?

listen its all language problem the more u spk hindi the more u learn of ur mistakes and the ways to rectify them...... btw u can make a list of pulling and striling words and memorise them so tat u dont make mistakes of ka and ki again

 thanks

its depend on your pronunciation mean just make diffrence in ka n ki in your mind
