Comment: Tilley's not a bad guy. He's not inspirational, but he does no harm. I have no feelings towards inorganic chemistry after taking this class. There are two major concepts which dominate the final and the midterms, group theory and molecular orbitals. Do whatever you can to understand them, the GSI's are a very good resource for this. Try to get them to do problems for you if you are confused. The class is slow paced and descriptive rather than rigorous. Be prepared to bring your own enthusiasm.

Comment: Chem 104a has been one of my most favorite classes in the Chemistry department. I thought 4a was awesome, 4b sucked, and wasn't the biggest fan of ochem (112A), so I was very much looking forward to this class. The first month or so is more or less review, but then the class takes a steep turn when group theory is introduced. It is an unorthodox concept and requires a very good geometric grasp in order to recognize symmetry elements. That being said, I thought that was one of the coolest parts of the class, especially the portion on bonding and different ways of looking at it. The class has some mathematical rigor, but nothing compared to 120A. The class presents a much more in-depth picture of MO and Valence bonding theory, as well as the SALC method using group theory. It presents a pretty good picture of mixing of orbitals based on symmetry, providing a much more clear picture of bonding. Many of the concepts in this class blew my mind, such as how using the SALC point of view SF6 only has 4 bonds, and 2 localized electron pairs, to yield a bond order of 2/3. The exams were pretty fair, but were clearly written by the GSIs, James and Billy. The first midterm was ridiculously long and hard, resulting in an average in the mid 50s or so. The second midterm was conceptually much more difficult as it had mainly bonding theories and group theory, but the exam was much more fair. The last month or so, the class delves into solid state chemistry, which had a lot of random facts and memorization. The final was quite fair but beware, group theory makes quite a big appearance all over the final. We never got to know how we did on the final however. The psets in this class are quite worthless, and are written by the GSIs. They are quite hit or miss, ranging from ridiculously easy, to insane amounts of tedious busy work. They do not help prepare for the exam much. The boom M&T is quite good for most of the class, and so is DG. Both the GSIs don't seem to care much about the class, nor are they that good at answering questions. On the other hand, Prof Tilley is quite good at answering questions and is quite thorough. He is quite a clear lecturer, although a bit boring at times, considering how long the lecture is. Billy is the more laid back of hte GSIs. Homework is arbitrarily graded again, where they pick a problem or 2 at random and grade them, and they are graded separately by the GSIs so people with same answers often get different scores. The class material is very interesting and worthwhile, but the class needs to be run better

Comment: This class consists of two midterms and a final. HW was a good indicator of the questions on the exams. I think the gsi wrote the exams. Professor Tilley is a good lecturer and answers questions that students raise in class. The material is pretty interesting to learn. We first reviewed vsepr and then moved on to group theory. Then, for the second midterm it was focused towards mo and acid/base. And then the last few weeks were on structure of solids and some trends in the periodic table. For group theory, the Vincent book is really helpful. Otherwise, MT and DG were good supplements for the class. The gsi's James and Billy were pretty helpful. They had weekly review sessions as well as reviews before the exams.

Comment: Tilley is a really good instructor. His voice is so soothing. His exams are quite difficult (probably written by GSI). The GSI sucks, but he is a very good instructor.

Comment: He makes the GSI's make the tests, and they arent familiar with the text book, hw, and barely the lecture, so the tests always end up being different to a certain extent. But the guy has solid lectures. They're clear and organized.

Comment: Very interesting class, but Tilley is just an average professor. He knows his stuff, but doesn't go into detail when you ask him questions, which for some is ok but made it hard for me when I had specific questions while studying. Exams were hard for me, but the books were interesting enough so I didn't dislike this class.

Comment: Professor Tilley presents the material clearly, but runs out of class time sometimes. Attend the discussion sections for sure. Leave a good amount of time to study the group theory and molecular orbital portions of the course because the difficulty level ratchets up significantly at that time.

Comment: It is probably the worst class I have ever taken at Cal. The entire course is so inconsistent. In the lecture, the instructor just threw out some random facts. The homework is not quite related to the materials on the exam. I had no clue how to study this course. The instructor and the GSI's provide little help. You are on your own.

Comment: This class has an inconsistent pace. The first third of the class deals heavily with MO theory of transition metal complexes and symmetry, but past that, this is essentially a class in descriptive inorganic chemistry. The materiel is presented in a non-rigorous fashion, which is frustrating because questions on exams can come out of nowhere, with few "first principles" to rely on to get to an answer when stuck. Still, the material is very interesting and rich. Tilley is a great professor for the rigorous material in 104A (symmetry and MO therory), but his laid-back style combined with the meandering feel of this class made things a bit difficult to really enjoy. This is really a shame, because I think Tilley is a great lecturer under other circumstances. Tests were fair. Don't let this course discourage you from taking 108.

Comment: Tilley really killed my enthusiasm for this class. Assignments were pretty useless, tests were easy. He threw a lot of random stuff at us during lecture that he never mentioned again. He was kind of funny sometimes, but 95% of the lecture time was incredibly dull. Also, he was really no help at all when I had questions.

Comment: Really spaced out person. his lectures are slow and random. he has his GSI's write the exams and do the majority of the work, so if the gsi's are bad, the class is pretty awful.

Comment: He's okay at teaching it. He makes it pretty enjoyable. Can't really hate or love the guy. HW and txt books were unrelated to the midterms so that got annoying.
