. I watched him throw a beaker at a student during lab and the University ignored my concerns and hushed the whole situation. I recommend you stay as far away as you can from him.Rate My Professors ↗

Quality 1/5Difficulty 5/5
Dr. Block manages the 103 labs extremely poorly and is not accommodating. It takes 6+ hours to complete 1 lab and worse if you are blamed when technology and equipment that's broken when you had no control to begin with. Labs are unclear, unforgiving and nitpicked on the poor wording to be used against you. Be very careful with him...Rate My Professors ↗

If I had just one—it would be to take this class again. If you are lucky enough to have Dr. Block, consider yourself blessed by the chemistry gods. He is a genuinely great person. You can tell he is smart—not just STEM-smart, but broadly so. I strongly encourage you to visit him during office hours; he has wonderful stories to tell.Rate My Professors ↗

Dr. Block is an amazing professor. He really cares that his students succeed and has very engaging lectures. He is very thoughtful and hilarious which makes his lectures fun to attend. He goes over different examples from what is given in the pre-class readings which really helps solidify what you read.Rate My Professors ↗

Chem 109 has a very difficult nature. The tests are incredibly difficult, much more than the practice tests given. Dr. Block is extremely knowledgeable in his field . The thing is Dr. Block says there will be an "adjustment" to grades at the end, but will not post it anywhere. You cannot see how much (if any) your grade was "adjusted".Rate My Professors ↗

I genuinely cannot say enough good things about Professor Block. He presented the material in such a way that it was so easy to grasp, and made you excited about chemistry. He cares about the success and wellbeing of all of his students, and is just a fun guy to be around.Rate My Professors ↗
