I had Costello first period. One morning, Coz came into class, and it was snowing out, so he turned off the lights and told us all we could just sit there, in silence, and "chill" it was the most relaxing 15 minutes of my life. Seriously one of the best teachers I ever had.

I loved Mr. Costello. I can already tell that years from now I will look back and remember him as being the best teacher I ever had. He is funny, smart, and possesses wisdom that can only be maintained by the variety of experiences he has.

He's a sick boss. He makes class exciting, he's funny and laid back. He really cares about all his students too and will take time to help you improve your writing, and give you lots of feedback if you ask. Best teacher I've ever had.

I can't stress enough how much effort matters to him. Even if you don't necessarily get everything the way he wants it, if it's obvious you tried, it will show in your grade.

Oh, Cos. He is such a fabulous teacher and is so passionate about what he teaches, and you can really tell in his lectures. I for sure learned a lot. He's such a cool guy to talk to, too.

Honestly, I think he's boring and it's only a fun class because I have my friends in it. I know everyone else liked him.. but I don't. Bowker was better.
