Brilliant professor and knows what she is talking about. However, on the teaching side, she can be arrogant on some days and helpful on others pending on her mood I guess. Doesn't really "teach" well, she's one of those brilliant professors in their field but not in the classroom. HARD CLASSMICROMICR 2013-01-25 12:19:24 +0000 UTC
Mixed feelings... she is brilliant and knows the material, but doesn't really TRY to teach. Sometimes she is really nice and sometimes she is condescending and arrogant. This class covers way too much material and she flies through it, then expects you to regurgitate every detail on the exams.BIOL2321 2011-12-11 23:51:39 +0000 UTC
The exams are extremely difficult. Read the text book before each class if you expect to pass. She explains the material well but covers too much too quickly. Do well on the final and in lab and you will get a good grade. Put more effort in to this class than any other.BIOL001 2011-11-03 20:36:56 +0000 UTC
Horrible professor made the class extremely hard. alot of tough materials to learn. tricks you with easy quiz but extremely hard exam. only two midterms so they are very intense and hard.BIO2321 2011-08-16 14:00:25 +0000 UTC
Professor presented quite the challenge almost to the point that it became miserable. She was helpful, however very arrogant. Advice: Pop Quizzes, 2 tests on 8+ Chapters, cumulative final exam, "microwiki", in-class presentation. !Uses textbook test bank - how creative.! Lab was interesting, however oriented for someone who has zero lab experience.BIOL2321 2011-11-28 02:03:46 +0000 UTC
This class will make you want to pull your hair out. High stress, recommend anyone elseBIO2321 2011-04-15 11:42:06 +0000 UTC
She made a somewhat tough course on par with Organic 2. Crazy amount of work, exams were really tough. She's barely engaging and when she does illicit response it's normally under pressure of some sort. Lectures were drawn out and mundane. She seems really smart but smart doesn't mean you can teach, too.BIOL2321 2011-05-05 03:59:13 +0000 UTC
Very high expectations of her students. Flies through material and difficult to understand at times. Exam questions are always very different from those she asks in class or quizes. Toughest class to date.BIOL2321 2011-03-14 19:40:57 +0000 UTC
