Summary:

We took the midterm exam today, covering Chapters 1 to 6 (Countings). Congratulations to Annabelle, Jason, and Susan for being Top 3 this time! (Max is absent because of his contest). Keep up the good work!

If you feel upset about the score, do not give it up. What more important is to learn from the mistakes, and find the area of improvement. Look ahead. I am looking forward to your progress in the following months!
