Sure! Here's an example letter in English about exams, detailing the subjects chosen, the ones to be taken, and how one is preparing, all within 80 words:
Dear [Friend's Name],
I hope you're well. I'm writing to share my exam plans. I've chosen to take Mathematics, English Literature, and History. My exams are approaching fast, and I'm focusing on these subjects. I prepare by studying daily, solving past papers, and attending extra classes for better understanding. It's intense, but I'm confident in my strategy. How are your studies going?
Best regards,
[Your Name]
