Well, you have covered a bunch of CR questions from the OG. If that did not help, repeating the same multiple times over is probably not the best strategy.
I would stop and ask yourself a bunch of questions - how is my question strategy? How is my understanding of argument components, etc.
P.S. If you are getting boldface wrong, that is a strong indicator your understanding of the argument components/elements is weak and you need to revisit it from whatever book/guide you learned how to solve CR's. If you just forced it and did not use anything, then you should use something. Doing thousands of questions is not the answer.
