It is the holiday and I’ve been having fun, so I forgot to contact you. I don’t think the AP Chemistry exam went especially well, but I got 7 in IB chemistry and 96 on the final too. Thank you for teaching chemistry to this rebellious student!

Teacher

Haha!

University of Toronto!

Teacher

Yes, I knew yours. The other student too? Amazing! Congratulations. It’s my first time asking the students. I honestly hardly know where anyone got in. Until now, I only knew about one student. I didn’t know where you were going either.

Student

The other student is going to Toronto too!

Teacher

Wow! Congratulations to both of you. Stay close, you two!
