A Dialogue between two Friends about Ensuring/Upcoming Exam

Ratri :  Good evening, Nishi.

Nishi : Good evening. How are you?

Ratri : Fine. Where had you been so long?

Nishi : I had been in my home.

Ratri : Why don't you come to the playground?

Nishi : I am busy with my ensuring exam. I am afraid of the examination.

Ratri : Haven't you completed your courses?

Nishi : No, I haven't. My preparation in English isn't so well. What about you?

Ratri : Don't worry. English is difficult for all. You have a sharp memory and I am quite sure that you will be able to cover up. But my preparation in physics is not good.

Nishi : Read physics more and more.

Ratri : Thank you for your suggestion.

Nishi : You are most welcome.
