Teacher talks a bit fast, and her notes are lengthy which makes it hard to understand the material when you are trying to listen AND write down notes at the same time. I was unhappy that she does not give a test review day or review session before exam. Instead, she will go on to a new chapter that is not on upcoming exam, confusing things more.

I really liked Dr Merkler's class. She works off power point slides but also uses material from the book so if you take good notes and read the book, you can do well. The tests are, by no means, easy so you have to study hard but you'll learn a lot. I highly recommend taking BIOL 95 before taking BIOL 189. I found that it helped me considerably.

After hearing the horror stories about the other teachers, I felt grateful. She does have stuff on exams not covered in class, but you can find most of that by reading diligently. I came out with a C, but I'm sure that's only because the lab boosted my grade, and I had only moderate effort. She's very spunky. I'd definitely recommend.

She is very nice, and truly knows a lot about biology! READ THE TEXT BOOK and her tests will be a piece of cake. She uses a power point with her lectures that comes straight from the book but doesn't cover everything that will be on the test. Her lectures are pretty interesting.

She's extremely nice, but a horrible instructor. Half of the items she goes through in class may or may not be on the test and if it is on the test it's worded as trick questions.

She does not stay on task during lectures, it is hard to study for exams because the notes are not clear, she is also not clear on the material of the exams, does not assign homework often so it is hard to understand the material, constantly changes due dates and is not clear on them, students cannot rely on the syllabus

Very knowledgeable, takes time to explain and help students after class, BUT her tests are very hard and at an expert level. Very important, take practice tests online and especially the ones linked with the Biology Campbell book it comes with! Pass those confidently, you'll pass the exams.

Best bio professor ever! Lectures were entertaining & engaging. Related the subjects to real life which made it relatable. Really flexible & willing to meet outside of class for however long. When I didn't get something, we'd go over it. Class will require studying a lot. There's no study guides, so make sure you understand the material for tests!

I personally do not think the exams are difficult, as long as you READ THE TEXTBOOK, do not just go off her lecture notes, chances are you will not pass. I got an A. I would take again

This is my second time taking her. She is not a bad teacher but she is extremely hard. She doesn't try to be hard but her 5 exams are tough and long. She also does NOT believe in study guides so it was really hard without it. Trying to write her powerpoints and listen to her lectures was a hard concept. Also, lots of homework.
