a letter of sympathy for your friend's failure in the examination.

My dear Ajoy,
I'm really sorry to hear that you didn't do well in the Madhyamik Examination. I know you weren't feeling well with the flu right before the exam, but I didn't expect it would have such a big impact.
Even though this is a sad thing, don't let it make you too upset. Exams are a bit like games of chance, and it's not uncommon for smart students to not do well sometimes.
And you know what? Maybe this setback could actually turn out to be a good thing. If you had gotten a low grade, you might not have been able to go to a good college, and that could have caused problems for you later in life. So, don't lose hope. Believe that you'll get a good grade next year.
Sending you my best wishes,
Yours sincerely,
Roger
