Reviews of professor Rainer Stahlberg

Rating: 2.0/5, difficulty: 4.0/5
Worst Biology teacher I've ever had. Lectures were long and confusing. Tests were based off of questions on his power points. Answers were not on slides, so if you missed a day, you did not get to see the answers. After moving on to other science classes, they refer to material I should have learned in this class but did not. Worst quarter ever.

I honestly enjoy his labs and the packets are straight forward. Lectures can get a little tiring but that's mainly because this is a 4-hour class. He sets you up for success with the study questions each week.

Professor Rainer was a good guy and gives you all you need to succeed in class. He wants you to participate as much as possible. His lectures are kind of long and the labs are confusing at times.

I highly recommend to study the chapters prior to the class as the lectures are covering the whole chapter. 
His lectures are very motivational and inspiring. Before entering this class, this was one of the pre reqs that I have to complete. After the course, you will realize how much potential in biology and makes you want to study.

Professor Stahlberg was a great teacher and his PowerPoints/lectures were fun, engaging, and packed with information. He encourages you to ask questions and dig deeper on the subject. He is always open to you asking a question to learn more and is always there to help. He gives you the study guides/questions to prep for an exam.

Rainer is a good professor. He is sometimes off track and hard to follow but if you show up and participate you will get a good grade.

I can feel his passion in biology and botany. That's the first and most important lesson I learned from him.
