Punajbi is not difficult to write.All you need to do is to learn some words that are repeatedly used while penning answer.Urban punjabi is much like urdu so feel at ease about complex words

.i am saying because had no prior knowledge of this subject neither it was my language but now i am quite fluent in writing & speaking punjabi

Only classical poetry & folktales are bit challenging but you can skip one part as there is choice between 2.Putting it in 2words "Punjabi rocks"


Besides it is good in fetching much needed marks
