Mr. Yellin is a good teacher. He's a little strange, but he is really devoted to chemistry and teaching his students.
he got chalk on his nose once. that was pretty awesome.
Great teacher, although he seems scared of anyhting that moves. Makes weird sounds at random. Very smart guy. YaY Yellin!!
Mr. Yellin is the sweetest teacher I have ever had. U can't blame him for his test after all is Chemistry
One of the most awkward men I've ever known. Excessively cool, though.
