Dear Mason.

Good morning, this is Donggyu Yeo.
I apologize for missing your phone call today.

I just want to briefly report my current status/progress to you and.. I would say 'so far so good!!'

I'm trying not to lose my pace so that I can make it before the deadline.
And every class you offer is decent and, not to mention, very helpful in improving my interpretation skills as well as my overall English proficiency.
Thank you so much.

Best regards
[Donggyu Yeo]
