Mr. Delahanty does not teach at all. He places you in groups and you have to work out the problems with them, which is difficult because no one knows what they are doing because he doesn't teach. He provides little to no instruction. He is a horrible teacher, and you have to teach yourself everything.

He refuses to answer questions, telling students to "ask your friends" even if he knows that they can't answer the question. STAY AWAY!!!

He is a pretty easy teacher and I did learn a lot from him, but his personality really irks me. He always snaps at his students for talking, even if they are talking during a time where they are not doing anything. He is also very unhelpful. Even if you go after school for help when he is there, you still won't get anything out of it.

I cannot stand this man. He is set in his ways and his way is "always the right way". He's irritating and impatient. Doesn't give good help, and doesn't explain things very well.
