我访问了Piazza的网站，并且看到学校老师对系统的评价，比如“Piazza被证明是我们班的理想论坛。”

Go to the Piazza site and read some of the testimonials from faculty such as this one: "Piazza has proven to be an ideal forum for my class."

这学期的自然科学课程对我来说确实很难，所以，这一门课的老师给了我所有学科里最差的评价我一点也不吃惊。

I had a really hard time with science this semester, and I sasn't surprised to find that my worst report was from my science teacher.
