While he's a nice guy, Mr. Margiotta has no clue about what he's doing. He can't teach the material well at all, although he's knowledable. He dosen't know how to control his classes so he gets walked all over.
Mr. Margoitta! oh my gosh. he's great, i came to class one morning in tears and kept sobbing all morning (huge fight with my mom, AHH!) and he was so nice about it all. i didn't want to take chemistry, i didn't need it to graduate, but my dad made me take it. fortunately with him it wasn't horrible, and he understands that chem isn't everyone's thing. he's very good natured and likes to throw in some of his own jokes. whether they're funny or not, it shows he's making an effort. he truly cares.
"It's 'Mr. Margoitta'!" He's a bit lax with discipline unfortunately but a really great guy who genuinely cares about his students. He's extremely helpful.
Poor guy, give him credit for trying though right. just learn to RELAX and figure out what you want to say before you say it.
