I do a semi-BR where I circle the ones I got wrong on the PT and redo those the next day. Ideally I'd do a full BR, but I work full time and just don't have the hours to commit.
That's the problem. You're scoring before you blind review. Circle any question you don't feel 100% sure on (99 percent is not 100 percent) as you drill under timed conditions. The next day, instead of redoing the ones you got wrong, redo the ones you circled without timed conditions, keeping track of your original answer and revised answer. Then compare your scores. I am almost positive this is what is keeping you from reaching your goal. You need to be understanding how you get to the right answer choice, and internalizing it. You also need to be understanding how you got to the wrong answer choice, and avoid that process. You need to understand when your intuition is operating to get the answer, and when the intuition works and when it doesn't. This will be a huge help on accuracy and timing. When you internalize *how* you get to the right answer choice, it will happen much quicker and much more effectively. Positive reinforcement for getting the right answer choice and negative reinforcement for getting the wrong one (what you are currently doing) will not be nearly as effective.
