People saying they don't like Dr. Roll don't belong in an advanced Micro lab. He is definitely disorganized, but insanely educated and helps students get to where they need to be. Treats students like real scientists, and actually prepares you for doing lab work. If you are a competent student that can problem solve, you will have no issues.Rate My Professors ↗
Very nice person but an awful professor. Always joking around; caring for students but demanding in grading. Quiz is impossible to study as it's focused on minutiae. MAKE SURE you understand micromath at the start of the semester! Lab manual is super confusing, and some labs require out of class measurement. Btw he once forgot his own appointment.Rate My Professors ↗
DO NOT take this awful professor, he never is prepared with his class, last minute finishes his planning. Grading is absolutely ridiculous, takes forever to grade. Doesn't seem to want you to do well in course, condescending and will make you want to give up the whole semester. Just actually worst professor in microbiology department.Rate My Professors ↗
Dr. Roll's assignments lack clear and comprehensive grading criteria, comments, and explanations, so it's easy to lose points in unexpected and incomprehensible ways, and difficult to modify. When you ask him questions, his answers are likely inconsistent, which is unprofessional. This will undoubtedly put a bad spin on your overall semester.Rate My Professors ↗
There was no syllabus for the class. The feedback he gave was practically useless. Avoid this guy unless you hate yourselfRate My Professors ↗
As a person, Jon is a funny and entertaining guy. As a professor, he's incredibly frustrating. His spur-of-the-moment teaching style makes for a disorganized classroom. Needless downtime was common. This bleeds into his grading, making it incredibly difficult to anticipate what he wants from you. The sparse feedback he gives is rarely helpful.Rate My Professors ↗
