For reference, I have only just finished the Section III of Gen Chem, but I have learned some valuable things about BR from the little time I've spent.
First off, you have to give yourself up. I found that when I tried to "do it my way" instead of following the logic of BR I would do poorly. For example, if you come across a concept that you think you know, but BR does it differently, do it their way. It really seems like they have made it their business to find the most efficient thought processes to excel. If you buy into them, and rearrange your mental paradigms you WILL improve by leaps and bounds.
Second, I am going through the section rather slowly. 2-3 days per section (although I haven't had Gen Chem in class for about 4 years). This allows me time to make the conceptual connections that are also necessary to excel. For every example and practice problem I am analyzing to see all the different connections that need to be made to come to the right answer. For example, I just got done with solubility and Ksp. The connection between molar solubility and Ksp didn't seem logical to me at first, but as I really worked on (both in my mind and on paper) the different tricky aspects just started to click. However, to fly through content review (assuming that its a weak area) won't help you. You can't answer a question until you have made the connections between concepts that are so important.
Lastly, once you get one wrong and figure out why, commit to never getting another question wrong for the same reason. Write them out, analyze what concepts didn't connect, and REVIEW these mistakes until you know that if a similar question pops up, you will immediately recognize it as if you saw it on America's Most Wanted.
That is my strategy for excellence. Some people aren't willing to put in that much for a stupid test, but that is my advice if you want to excel. See you on the other side of 40.
