Hi Richard, have you tried reviewing what areas you get right and wrong and which topics you are more confident with?
The best value that can be extracted from the practice tests is the "feedback loop" - so I would suggest tabulating which topics you consistently perform above average on and which ones fluctuate.
That is a sign that you would need to invest more time into the topics where you see inconsistent performance. You can review the study materials or deep dive into specific topics with a friend or study-group, etc. once you hone in on which areas you need to focus most on.
As for San Fransisco specific study groups, I do not have any suggestions, but you could look up online study groups nevertheless once you identify your focus areas.
