Poor

If you're an undergraduate statistics student of CSULB, chances are you'll take more than half of your courses with Doctor Korosteleva. All I can say is, I'm sorry about that. She's nice and makes herself accessible for students. However, even with her good character it doesn't guarantee that she's a good teacher. She's bad at teaching and feels all over the place. Sadly, my learning experience under her was poor.

Self-study goes a long way, because taking Olga's class means you're mostly on your own. She was a nice person, however she'll never admit she was wrong. Good luck learning something from her, she does not communicate her lectures very well. She grades easy, which is probably because she knows she doesn't teach very good.
