Professor Abu-Omar is very funny and approachable. I STRONGLY recommend going to his office hours -- he even has a couch in his office. But beware -- just because you did well on his first midterm doesn't mean you'll do well on the second. He usually gives you a good idea of what'll be on the test.
he's really good at explaining some things (like organic) but terrible at others (like orbitals - the TAs did better jobs). he's super easy, a really nice and funny guy. tests were just like homework problems, if not easier. pretty fair grading, but his system favors smart flakes (which ticks me off a little). i enjoyed the class.
