I took Berkeley Review this summer at the UCLA center and I thought it was incredible. Todd is fantastic as the others have already said. Todd taught most of the G Chem and O Chem at my center. I thought all the other teachers were knowledgable, but like any program each had their own personalities and style. The 2 hour lectures were extremely helpful to me because it has been six years since I've taken many of the courses. Therefore, if a two hour lecture on a topic I hadn't heard or thought of in six years worked for me, well then people that have just finished these classes may find them unneccessary, so you must make a decision on how much review you need. I used all the materials the class provided, including extra problem solving sessions and office hours. I found the office hours to be very helpful, especially Todd's and Moin's (physics). Every topic that they emphasized would be on the test - was on the test.
My thoughts on the verbal passages are that they are much longer than on the MCAT, but if you can make it through a set of BR passages without running out of the time the MCAT passages become much more managable. On the test, I got completely through the VS and didn't feel rushed at all.
I scored a 30 on the August MCAT and I believe that for me without the BR lectures, passages and teacher support that it would have been a different story. I had taken the MCAT two years earlier and reviewed on my own with another company's material and well it took me two years to get up the courage to try again. So, you really have to decided for yourself - Are you the type of person that needs an organized, methodical, review and passage oriented approach for studying for the MCAT? Then BR may be for you.
