I was wondering about the best method to increase one's score. So far, I see that many people recommend reviewing the questions wrong or drilling more of it. I see little to do with question difficulty—I think this would be helpful. For instance, say you do a prep test, and you get a combination of wrong answers in logical reasoning such as Flaw, Parallel Reasoning, Weakening, and Must be True; from then, you look at each question's difficulty, and they range from 2 to 5/5. Now, let's assume that you notice a trend in that you cannot get past 3/5 difficulty in Flaw questions. Would it be reasonable to conclude that by drilling 2/5, in difficulty, Flaw questions until you achieve high accuracy, like 90%+, be a better way to improve and move on to the next difficulty? Even more so by reaching ideal times before moving on. I am trying to find methods that work for me, and it would be awesome if you have something to add.
