Hello,
I think your flashcard is nicely structured and full of valuable tips for test takers. Yet, I believe that one of the cards (in page 8) about "Correct Sentences" is not necessarily valid.
While it is true that 20% of the correct answer in Sentence Correction would be the original construction of the sentence (choice A), we cannot imply from this fact that the number of questions having choice A as the correct answer is approximately 3 out of 14-15 questions. It appears that, in that case, we simply take the 20% rule and apply to the number of SC questions in the GMAT to obtain the approximate number of questions with A as the answer. In fact, we don't know the probability of the questions with answer choice A as the correct answer. What we know is, for every SC question, there is a 20% chance that the correct answer would be A.
Consequently, the probability of having 3, or 4, or 5 questions with choice A as the correct answer out of 15 SC questions should differ from one another.

Ronald
