I just took an exam in my first semester inorganic course. I do all the homework with out too much trouble and read the material but the problems on the exams are out of this world. They are nothing like the assigned problem sets and the problems in the course book . I've gone through the standard " 3000 chemistry problems solved" and the book we are using in the course is, according to the instuctor, an advanced text. From what I've learned in my three semesters of calculus is that the only way to really get the material is to do as many problems as possible. The difficulty I'm having in chemistry, I know, is that I can't find enough challenging problems to practice with. Does any one know of a good advanced chemistry problem book? I'm just looking for a supplement to my text which is Zuhmdal's " Chemical Princilples". Just a book with alot of problems.
