Sounds like you are doing a good job to me, since their scores were higher than state averages last year. The bunch this year will probably surprise you next year.

Teaching is one of the most important professions and so underpaid considering the charge of the profession, i.e., developing the little minds today to lead tomorrow. I am glad to know some kids have you as their teacher!

Keep up the good work and enjoy the rest of the year. It takes special people such as yourself to teach.
