Comment: A decent instructor. My biggest gripe was that he stopped posting "skeleton notes" as the semester went on. Other than that, his lab lectures were all right. Lab exam was fair, easier than practice exams.

Comment: Exam was pretty straight forward compose of simple calculations. He posts outlines of his tablet powerpoint for you to write on and follow along. He has messes up with he talks but it'll go away with more experience.

Comment: I took this class during Viernes's first time teaching the class. He was very clear in his explanation. I like that he writes the notes during lecture after he has already posted them.

Comment: Very clear, very thorough professor. Viernes explains difficult concepts and mechanism very well. The course was organized so that each section built upon the basics that were learned in the one preceeding. Posted skeleton notes online that were easy to follow during lecture. Took questions during lecture, VERY helpful in office hours, has a great sense of humor and posts pictures of his various pets on his computer. I can honestly say that I learned more and better chemistry from him during summer session than I did with Frechet in spring. All in all, a great teacher, with very fair tests!

Comment: Lab Exam was super easy, the labs and lab reports are almost all really easy, too. There are a few tricky questions/NMRs on the reports, but you can go to GSI office hours and get help, so it's no big deal. Overall course was good. A lot of Chromatography. Pretty much no more in-depth NMR than 3AL. IR was not covered. Lots of Mass Spec was covered but not really tested on other than one worksheet in labs. Pop quizzes are kinda annoying but generally easy. Fun labs!
