I had another teacher before but I switched and the one I had before was amazing. I switched and I think that if your a "teachers pet" your grade might get higher because your the teachers favourite.
But I'm not but my best friend is and I don't mind, but she gets higher marks than me and it seems like my teacher doesn't really like me. She doesn't really say hi to me when I say hi to her but when my friend does she starts a conversation with her.

I don't care that my friend is her favourite but I'm just concerned about my grades! I used to get 90s but now I'm getting 80s and I've never really gotten that before. I'm trying my best I'm studying but I don't know :(

please help me give me some tips and experiences thank you so much
