Query: I feel disappointed with Osborne's exam titles

I bought a few exam books from Osborne for my Oracle and MCAD exams. The oracle one, I have nothing else to say but "incomplete" coverage. Well, I thought it might be the author's issue, so I bought this book for my 305 again. After reading the first half (350 pages), I feel my $ was wasted again. The content is not well organized at all and errors are everywhere (I even doubt the authors speak English well). For code example, forget about it. I have to buy another Wrox book, "Professional Vb .Net (2nd)", to make sure I'm OK with the test objectives. I think Osborne is shooting its feet for publishing this "rush and dirty" books without serious review. For me, this is the last book from them, definitely.
