Today i saw another class 5. she wasn't bad at all, the hardest part was that she didn't speak a lick of english. So anything I saw or wanted to mention, she had absolutely no idea what I was saying. We had her OD done from a time before though so she was pretty quick other than coming 20 minutes late. She had a lot of build up on the lower linguals but it was not real tenacious. Pretty good patient over all.
