I didn't do too well on an assignment but i still felt like i could improve my grade for the final exam
I only got a B- on an assignment i worked really hard on recently, but i'm working even harder now studying to ace the exam!

Wow! I'm sorry to hear that. Do you think you will get an A this time?

 I do actually!

Congratulations! Studying can be hard, but sometimes it's about technique rather than time spent. Are you doing anything different this time?
