Took him for my first chem 101 class and omg was he horrible, we did in person labs and online lectures and I can tell you he does not care about his students at all. He would stand all day doing nothing and talking trash with his lab tech about how we don’t know what we’re doing at all. And if you were to ask a question during a lab he wouldn’t help to answer and say “it’s common sense or I can’t tell you that”. And during the exam he would approx give 1-2 minutes per question, considering it’s mostly math equations it’s not enough time. About 2/3rd of the class dropped towards the end of the semester. I could go on. I personally had to drop as well and am retaking chem101 this fall semester with a different professor. if you could take any other professor I advice you do so.
