BR them. Shoot for perfection. Make sure you understand why each answer is correct and incorrect. Then watch the videos to devise a strategy of knocking that game out under timed conditions. Then foolproof it so that it becomes intuitive.
No. I personally do not watch these videos, but that is in large part because I understand them when I do the tests and also have the BR groups to alleviate any lingering misapprehension.
Your mileage may vary (see I stole it, @Pacifico ).
Thank you all very much for your input. I will stop PTing and head back to the curriculum again. When I went through the curriculum second time, I didn't watchall JY's solution for the problem sets. I will do that this time. Thank you :)
