Hi
Sam10smart, unfortunately, there is no straightforward answer to your question. It could be that you just need to fix your time management & decision making (which questions to skip), but generally speaking these are not skills that one can develop in a week. Usually, this skill comes during practice when you solve a significant amount of questions. While solving questions and covering concepts, you develop an internal database of common questions types and, assuming your fundamentals are solid, you gradually become better at solving questions that are twisted (use strange or unfamiliar wording).
My recommendation is to focus on fundamentals. Also, try to find a question categorizer for
OG (I am sure you can find something from Manhattan or other courses), and go topic by topic. For instance, go through all ratios and percents questions, then go through Word Problems, then through Algebra, and so on. If you notice that you miss a significant amount of questions of a certain type, say ratios & percents, then you will likely need to study that topic in more detail. There are plenty of good materials out there. Many people recommend
TTP course for Quant, so you may look for reviews.
Basically, the better you become at standard types of questions, the better your timing will be. And then, again, you should work on developing good decision making skills, i.e. when you see a new question, you must ask yourself (1) "do I know what subject is being tested?", (2) "do I know how to approach the question?", and (3), after you try to solve for about 30-45 seconds, "am I getting anywhere?". If you are not getting to an answer and feel like you are getting stuck, you should not continue. Guess and move on.
