Sure! Here's a message you can send to a friend about school in English:
Hey [Friend's Name]!
Hope you're doing well! I just wanted to share some thoughts about school lately. This semester has been really busy with all the new subjects and projects. I’ve been enjoying my [favorite subject], but [another subject] has been a bit challenging.
How about you? How are things going in your classes? I’d love to catch up and maybe study together this weekend. Let me know if you’re free!
Take care!
Best,
[Your Name]
