Rated 5 out of 5 by from Great explanations The professor makes this so easy to understand. He is down to earth and gives examples that I can understand. It also helps that I can replay parts that are difficult for me to grasp the first time. Best investment I have made.

Rated 4 out of 5 by from Great for what it is I have an extensive chemistry background so I already knew all the material, I understood it immediately, and had no difficulties with any of the problems. I just bought this this as a review and it was great for that. However, it is great in a restricted sense, it’s great for what it is, which is essentially a long course in how to do high school chemistry problems. The instructor is fascinating and engaging so the lessons move along in a very interesting way. However, I feel it doesn’t so much teach chemistry as teach, in a very accessible way, how to do elementary chemistry problems. If that’s why you’re buying it, you’ll love it, this guy can really teach. If you want a broad view of chemistry, you really won’t find that here.

Rated 5 out of 5 by from Fullfilled Bucket List I am 73 years old. Retired Healthcare professional. When I took General Chemistry in 1966, my professor was so confusing to me that I had to limp through future Chemistry classes the best I could. I made it, but I never really understood General Chemistry, so it has been an item on my retirement bucket list to retake and understand General Chem. Thank you Mr. Cardulla for making the subject understandable for me. I have a much better understanding of what goes into the making of the products I consume as an adult. Your methods of explaining really clicked with me and your attitude toward my learning was much appreciated. I hope your life is going well too, and know that an old dentist in Idaho achieved a great satisfaction from taking your course. Well done.

Rated 5 out of 5 by from Makes a difficult subject understandable I am a 72 year old learner and I studied chemistry in high school and college but I didn't have an overall understanding that I thought I shold have. Mr. Cardulla has a unique ability to make a difficult subject understandable and makes the the pieces fit together. I recommend this course for anyone needing basic or beginning chemistry.

Rated 5 out of 5 by from Former Student Mr. Cardulla was my Sophomore Honors Chemistry teacher at Niles North High School in 1999. His class was much harder and challenging than AP Chemistry I took by a different teacher 2 years later when he moved from Niles North and started teaching at another high school. Maybe he did so well at teaching basic chemistry that AP Chemistry was a breeze? I don't know but he was the best teacher I ever had although I did not like him at all as a sophmore!
