Write a letter to your friend advising /requesting him not to adopt unfair means in the examination.
Dear Nisha,
I hope you're doing well. I got your letter and it made me happy. I'm really glad to hear that you're getting ready for your upcoming SSC exam. I believe you're going to do great in the exam. This is the perfect time to get ready for it.
You know, these days some students try to cheat instead of studying. They use dishonest methods in exams. But doing that won't make them truly smart or educated. I want to warn you: please don't ever think about cheating in the exam. Cheating is like doing something very wrong and it can ruin a student's future. Even if someone passes an exam by cheating, their life ahead can become very difficult. It's better to fail in the exam than to cheat. If you don't pass this time, there's always another chance. I think it's better to face failure than to cheat. Listen to my advice and you will do well and gain from it.
That's all for today. Say hello to your parents for me and give my love to your younger siblings.
Take care,
Samia Rahman
