Comment:

Great instructor. I took his chem 115 during the summer, not too much work like I expected. He's very smart and his class is fun especially the lab. Gives a study guide before each test and the tests are very similar to his study guides. He also would make sure you got the material before the test. Would definitely recommend him.

Great teacher but definitely read the book, take tutors, and ask as many questions as possible. The study guide isn't like the actual tests so know all the concepts instead of the equations.

Comment:

I enrolled his class this summer 2017, but after two days I've decided to drop it. He seems nice to say the least, but he is not an effective educator for me. He can be a chemist, but not an educator, as he does not know how to explain the materials in the level that the average students who do not have chemistry background can fully understand.

Comment:

Don't know why this was labeled 'Forensic Chemistry', as it was primarily a general chemistry class. He was not good about announcing when homework was due. It was a fast-paced class, if you didn't understand something, there wasn't much time to catch up. He had office hours, though I never went to them. Passed by the skin of my teeth.

Comment:

Jeff is an awesome individual, but he is not the best teacher. I had him for chemistry 142 (gen chem 2), and he was horrible. He grades everything like grammar to sentence structure on timed exams!!! The only way you will pass this class is if you have his old exams because the practice one he gives out is nothing like the exam he actually gives.

Mr. Lehman is a great professor! He made Chemistry a lot easier for me to understand. It is easy to communicate with him through email, and he is also very approachable in or after class. there will be weekly quizzes, and you have to sign up for sapling learning for the HW. He also brings cookies from time to time! Overall, great experience.

Really cool guy, great sense of humor. He explains concepts very clearly, and will answer homework questions if you ask. His classes are very interesting, and labs can be a lot of fun.

Comment:

Jeff loves chemistry and knows his stuff, obviously! he teaches the subject, but I only mention it because I feel that sometimes he forgets to talk about the basics. Chem 115 is a starter class for chemistry and you are not expected to know much about it, but I feel that with him, that is not true. I passed the class.

Professor Lehman is a HARD teacher. I took him for Forensic Chemistry (113), and it was the hardest class i have ever taken. At no time in the semester did he update our grades onto the last day of school, so keep track of your scores. Quizzes at every start of class. You can pass the class with a C+ and not pass the exams. START A GROUP A.S.A.P.!

Professor Lehman is a great teacher. Attend class. If you fall behind it's hard to catch up. He gives pop quizzes. They are short and used to make sure you understand the material. He has a good sense of humor and he cares about your success.

I got over 95% in homework, quizzes, and labs. I got an A - (the first in my life) because exams are IMPOSSIBLE. I never got more than an 80% on the tests because they were so hard. It didn't matter how much I studied there was always something I don't know. But, if you do well in everything else you can definitely pass.

Comment:

To be completely honest, professor Lehman is a very intelligent and likeable teacher. He is an extremely critical grader and he expects you to have read the textbook chapters before his lecture, which you should do or you'd probably be lost if the subject doesn't come easy for you. Test are difficult to say the least. Find a study group stat!

cool guy. reminds ya of a dude you went to high school with. tests he's not too tough on ya. you will notice that by the end of the term more than half the class has dropped, but mostly i think its because its chemistry, whatever you think is right in the normal world, its the opposite in chem. lots of homework. push and get thru it.

Comment:

Jeff is really laid back. I am a business major so I really am clueless in chemistry. But he knew how to teach it and I learned so much & retained the info. I was proud I passed because of his method. Labs are at night and they are very helpful on exams. Study and practice each day. Ask Questions. He curves on a weighted scale.

He is an awesome professor, towards the end of the semester I realized how much I have learned and all that he actually helped for me to learn by providing a lot of chemistry simplified and by doing this enabling a much easier cognition of my learning. I realize it may not be helpful to everybody, as it varies from student to student.

Mr. Lehman is one of the best professors at Grossmont college. He knows his stuff and does his best to make sure you understand the material. His class is a bit challenging though... his exams are kind of hard but he's always there to help if you need him. Take him if you're willing to put your effort into the class and read the textbook.

Comment:

Mr. Lehman is by far the best chem teacher at grossmont/cuyamaca!!! He truly cares about his students and is good at explaining concepts to make it easier to understand. However, his exams were usually a bit of a surprise...they were difficult and worth a huge chunk of your grade. Make sure you read the book and I took him for chem 141 and 142.

Lehman is one of the nicest people ever! Chemistry is hard no matter what ... Few things thou: he does NOT curve and he averages percentages not points. All in all, if ur taking him, keep in mind that he is the best of what Grossmont and Cuyamaca chemistry departments have to offer! I'm sure going to miss his class.

Comment:

Best Chem teacher I've ever had. 4 exams, 1 final, 20 quizzes (drops a few), many lab reports, graded online HW(time consuming). I didnt use book at all! Lectures are very helpful. Gives practice exams prior to actual exams, which are almost the same :D Pay attention in class, dont miss lectures, and you'll be fine! He curves. I got an A.
