Microbiology: His tests are hard but he's a good teacher. Going to class is important because most test questions are based on the material covered in class. Textbook has a lot of extra information, but only a few test questions will be based on stuff not covered in class.

Great prof. One of my favs. He explains everything very well. It is such an interesting class. He will go out of his way to meet with you and help you understand and do better on tests.

I really did not enjoy this class. I found his lectures were very boring, and hard to follow. The notes were a mess, and did not always make sense like Structures & Functions.

You can achieve an A if you go to every class, take good notes, and study at LEAST 1 hour every night. I got an A in this class by doing this. It's hard but you can get an A if you put in the time. His tests are also very very very in depth. He might mention something once in class and it could be on the test.

Basic Microbiology isn't a very difficult class, but it's pretty boring, so you have to pay attention. The exams are all multiple choice- some questions are simple, some are very detailed.

I had Dr Leff for Microbiology. He really is a nice man, but he gives lecture outlines and then does go over them in class. You should go because he will say important things that aren't in the notes. There is soo much in the notes, but then when you get to the test, it is almost too narrow and I think he does add some book questions. Iffy to me.

Microbiology is hard there's no doubt about that. He doesn't make it any easier. You can buy an access code for 80$ for 5 points of extra credit before every exam, 20 total. Its expensive and you probably feel reluctant to buy it but if i didn't buy it i would've gotten a B. He has 4 exams and that's all so you have to do well on them.

He's alright I guess, his study guides are more like outlines and he doesn't give a clear idea of what is going to be on the exam. Sometimes things covered on the exam aren't in the review. Meaning you HAVE to read the chapter in the text book. Exams usually cover 3 to 5 chapters and chapters are around 25-30 pages long. Makes a core class harder.

Memorize, memorize, memorize. Memorization is key to doing well on exams. And, if you don't do well on those exams, good luck on bringing your grade up.

Micro is a difficult course to begin with, but make sure that you know everything in lectures, take good notes, and utilize the textbook to better your understanding of the material. He provides you with lecture outlines, figures, and responds to e-mails fast if you have questions. Utilize all resources & you will succeed. Otherwise, good luck

Dr. Leff is an extremely smart man. He loves what he does and it really shows. I had him for Biological Diversity and this class is a lot of work. You need to take good notes and get ready to study because it is necessary to be successful on the exams. I had his class during remote learning, so it was slightly different. Overall, good professor!

Make sure you read his outline and take good notes of the lectures. My only complaint was that your grade is based of 4 exams. But he does a good job of explaining material in his lectures.

He is a very lecture based professor. The grade is based on only 4 exams, so be prepared to study, hard. Take a notebook, and not only write down the slides, but what he is also saying as well as he tests on things he says, and on the finer details. This grade will take a lot of studying, but is passable.

Worst class Ive had yet. Boring lectures that drag on, way too much material to go through on each exam. On top of not being open note tests, I had easily 20 pages of notes per exam to look through. Good guy by all means, just not a good class to take in the middle of a pandemic. So goodluck!

Dr. Leff is a very uncaring person. His lecture videos are over an hour long and without watching his videos, you will FAIL his exams. Everything he says will be on the exam!! This class is more about memorization than actually understand what is going on. His class only has 450 points and the four exams are 100. you can't fail an exam or its over.

Take good notes, Cornells notes actually. Dont waste your time feeling overwhelmed with the material. Trust the process and take notes based on everything he says. Then, the next day go try to understand the material. Then, when youre done, make flash cards called anki. This class is pure understanding combined memorization. Its an simple A+!!!

He clearly did not transition to online school well at all. Hours upon hours of lecture videos every week, 4 weeks between each big exam, 4 exams (add up to 400 points), and 4 quizzes (worth 5 points each). You seriously have to watch the lectures & take note of what is on the slides AND what he says. Doesn't care about his student's concerns:/

Dr. Leff added about 3 hours of lecture every Sunday, so make sure you watch them. His tests are straight from his lectures so good notes are a MUST! This class is just memorization so as long as you can memorize notes, you should be fine. There were only 4 exams so you have to do well on each exam in order to keep an A. But overall, its not bad

I personally worked my hardest, and considering the difficulty of this class, I am not upset with my grade. Dr. Leff does not hold office hours also.

I've had Dr. Leff for two different classes, and I've learned the most from these classes than any other classes at Kent. His exams are challenging, and you have to watch the lectures, but he explains difficult concepts well. The grading criteria and expectations are extremely clear. I wish I could take all of my science classes with Dr. Leff.

I took Adan Leff for Microbiology and in my opinion, I found it difficult. If you are someone who struggles with science, I recommend you pick a different professor. There was a total of two quizzes and four exams which made it harder to bring up your grade. There are no homework assignments or extra credit, so don't waste your time asking him.

Leff has been by far the most difficult professor I have ever had. I took bio diversity with him and struggled immensely. If you want a good grade you will have to spend hours everyday of the semester studying. He was not helpful to students and seems to not care about his students succeeding. He provides no material outside of lengthy lectures.

I made quizlets based off the outlines he provides and did well on all of the exams. Just don't procrastinate! He even says in lectures what you should specifically focus on.

An overall great guy, however, his lecture material and his exams are extremely heavy. There is A LOT of material he covers, so studying just one or two nights doesn't cut it. Take a few weeks to review his material, and go to SI and tutoring. exams 50 questions each & 2 online quizzes, so you don't have much wiggle room! Prioritize your studying!
