He is very smart but a terrible teacher. Instead of teaching he makes fun of you for not knowing the answers. He expects you to have the chapters memorized each day. I don't think he understands that we haven't been studying this for more than 10 years, like him.

Dr. Grubbs is great. O Chem is a hard class, and it takes a lot of time to understand it. But Grubbs is more than willing to help out. He is very un-approachable, but thats just his personatity, He's not the bubbly type. Put in your effort, and He'll help you out

Dr. Grubbs hosts some of the highest quality classes at GCU. Want to get into Med School/Grad school/pass the MCAT? Take his classes, but expect a Grad level class. He doesn't hand out A's. If you want it you'll need to put in the time and seek help if need be. Those who complain about this class probably aren't cut out for further education. A+ !

Dr. Grubbs uses the opportunity of you being in his class to prepare you for your graduate exams. His class is extremely hard, and you will study intensively, but you'll be grateful later on. When I took the MCAT, the OCHEM portion was actually easier than most of Dr. Grubbs exams. If you put effort into succeeding, he'll put effort into you.

The course is challenging, requires a lot of effort, good time management. He makes you do the HW problems but does not grade them. He gives you old quizzes and exams that help a lot. Do them before the review sessions. I got an A in OCHEM I so OCHEM II was not that bad. The course no longer has a curve and this makes it harder to get an A.

The professor gives students all the resources they need to succeed. Read the textbook and class handouts, as we were tested on both, however, many students did not read the textbook. Review handouts for tests, as many questions have a similar process. Also make sure that you go to the review sessions he holds. More enjoyable than general chem.

Grubbs is the best professor GCU has, he cares about his students and provides more then enough materials for you to do well in this difficult course. Provides step-by-step instructions when showing new material. Also, it says a lot when a professor takes time out of his summer to have several review sessions a week through out this short course.

It blows my mind to see that so many people like Dr. Grubbs. He is honestly a horrible teacher -- he stares at the floor while pacing around the room, reciting pre-meditated lectures and pitiful jokes. There is no doubt that Dr. Grubbs has IQ of about 200, but he lacks social skills and every desirable quality one looks for in an educator.

Gubbs goes through many practice problems in class and effectively uses class time to get through the material we need to know. His review sessions and warm-up problems prepared us for hard exams. You have to actually learn. His knowledge and humor with the subject is amusing and elicits interest in the subject. I'm looking forward to CHM-232.

This is the best class I have taken at GCU. The information is clear, and he continuously emphasizes what you should focus on when studying. This was the 7-week summer course and obviously fast paced; If you do not know something, just control find the word in your textbook (it never fails). Typing out notes is necessary!

If you want to pass CHM113 and understand it, do not take his class. He is funny and a good person but he does not explain things well, his lectures are so boring, and he doesn't answer questions well. Your best bet is going to office hours after every lecture and getting a tutor. Never have I cried so much, good luck.

Overall, I thought that Grubbs was a good teacher, his participation worksheets that we did weekly, were very similar to what was on the exam. I felt like he did a good job going over everything that was on the tests, and his tests weren't too difficult.

Grubbs is a good person and does have a lot of cool tips to remember the chem materials. However, it'd be a lot of extra work since he move fast-paced with lecture. Half of the class usually going over participation, quizzes and midterm are much like the participation. He's accessible outside of class but he does make me feel bad asking questions

Dr. Rubbs teaches with passion and intensity. It's as if he is playing a championship basketball game with the game on the line. He challenges the student in ways I did not expect. I appreciate his dedication and his thoroughness but do wish he would smile more as he comes across as intimidating.

He was rather dry and didn't engage with the class much, but he was good at teaching. The participation worksheets were super helpful because they had very similar content to the tests on them. He would also make students do the problems in class, then go through them, which was incredibly helpful.
