I wasn't expecting much going in, but he is a fantastic professor (and I don't use that word lightly). I didn't buy the book, yet with casual readings of the Zumdahl in the library and his lectures, I feel as though I completely understand the subject and what I need to improve. He is soft-spoken, but clear and you can tell he loves the subject.

Very nice professor, when it comes to grading, he really will give you better grade that you deserve, but you do have to study, no multiple choice, which will make you smarter, after all it is a science course. You can study based on his previous test which is very helpful. He will answer if you ask. Defiantly recommend, but you do have to study.

Professor Lloyd is an amazing professor and person in general. Make sure you take his class for Chem 12. He is thorough and understanding. Makes chemistry way easier to understand. The grading is fair. You do the work online and it sets you up very nicely for a good grade.

Amazing professor. Very nice demeanor and caring. His grading of labs is good, and I was able to type out reports with confidence knowing that he'd be able to correct me. Or at the very least, give some insight. I was also able to ask for help with acids and bases, and he was great at explaining the concept. Wish him all the best!
