Great to see you again! The lesson was very interesting, and I enjoyed experimenting different lesson plans with you! Keep them coming!

Great, job, Jack! Again, your pronunciation is very good and you have an excellent ear. The only English sound that is, (and probably will continue for a while, as for most Asian speakers), a challenge is the "dark L" sound that occurs at the end of many English words. Pick out words that have this sound, make a list, practice them and record yourself. With time it will be more natural and easy.

Nice meeting you. Hope to see you in class again.

Unfortunately Jack missed the class, but I hope to see him another time!
