The 174 labs themselves are not very difficult, although the pre-labs often require information that has never been covered in class.  Lab reports are what make 174 hard.  There is a written or oral lab report due almost every week.  Often these require six to ten hours just to understand the data analysis.

He doesn't take attendance but you MUST attend every lecture because the material is incomprehensible from handouts and there is no textbook.  The topics covered in class, largely the quantum theory behind various forms of spectroscopy, brings together much of the material from all the preceeding lab classes but it is also difficult conceptually.

Professor Khosla would be an engaging lecturer if the entirety of the content was not taken directly from the textbook.  If you can read on your own then really only the Wednesday lectures about disease biochemistry are worth attending.  Even those are hit-and-miss.  The lectures on less common diseases are usually good and include detailed biochemistry.  The lectures on diseases like cancer, AIDS, and malaria are so basic that anyone with even a passing interest will already know the material in greater depth.  It is laudable that Professor Khosla tries to teach general principles instead of piling on specific information to be memorized.  The exams clearly reflect this approach and they test very little rote memorization.  Overall the material here is important for anyone interested in research in biochemistry or molecular biology, but the class itself is not exciting.  If you have specific interests then you would probably do better to take the relevant classes from the Medical School or Department of Biology.");
