An effective long term goal for Critical Reasoning is to solve most questions in under two minutes. A useful breakdown is to read the argument in about 30 seconds, spend 15 to 20 seconds pre thinking possible outcomes or gaps, and then use the remaining time to eliminate choices and arrive at the correct answer. This is the stage you eventually want to reach to handle the Verbal section with both speed and accuracy.
That said, it is completely fine if you are taking longer during practice while building these skills. Your first priority should be accuracy. Once you can consistently get questions right using a structured approach, then start tightening your timing. If reading itself is slowing you down, try reading more outside of prep such as news articles, blogs, or books to improve speed and familiarity with varied vocabulary. You will also need strong analytical thinking to pre think effectively so you do not get stuck rereading answer choices. You can refer to my “How to Improve Verbal with AI” guide for methods to strengthen pre thinking (link is in my signature) and identify gaps in the CR argument. As these habits come together, you should begin to see consistent high accuracy within the two minute window.
