Last year my chemistry teacher sucked. She spelled mammal "mammmal," more "mor," calculator "caluculator," and many more. She had no idea what she was doing, and it took our class a month to go over sig figs, while this year in physics our teacher (who has a PhD) went over sig figs in about a day, and explained it about a hundred times better.
We couldn't say centimeters cubed, because according to her, it would be like saying "ball red," and she required that EVERYTHING we wrote would be in "black ballpoint ink," otherwise we wouldn't get credit for our work.
At first we thought moles were something she made up off the top of her head because she had no freaking clue what they were, and she called everyone Mr. or Mrs. <insert last name here>, and knew NONE of our first names.
On her vocabulary tests, she required that every word was spelled perfectly (even though she blew at spelling herself, see above examples). Once on a vocabulary test, one of my friends wrote in cursive. She checked every single word wrong that had an "n" in it, because she thought that cursive "n"s looked like "m"s, and blamed it on her eyes, refusing to change the score.
I could go on for hours about how horrible this chemistry teacher was.
So I definitely know a thing or twenty about bad chemistry teachers, and I feel your pain.
