Verbal Reasoning and Quantitative Reasoning sections are both adaptive. This means that, in each of these sections, say e.g. in verbal reasoning, if an answer is correct then the difficulty level of the next question increases. Similarly, if an answer is incorrect, the difficulty level of the next question remains the same or goes down. The final score for these sections ranges from 6-51 and is calculated based on the number of correct answers and difficulty level of the questions. There is a penalty for not completing all the questions in these sections.
