My Dear Your Brother Name,
Please take my blessings, I got your letter. You have asked me to write about my subjects. I am writing it below.
I learn seven subjects in my class. They are English, Sanskrit, Hindi, Mathematics, Science, History, Geography. In Mathematics I learn algebra, Arithmetic, and Geography. In Science, I learn only Botany. English is my favorite subject. I also do well in all other subjects.
Please tell my respect to our parents.
Your Eldest Brother
