Can I believe it with 100% reliability?
1. Do I have to get ALL Quant questions right to Q51?
Answer: not all but you have to get to hard questions and to do that you have to answer 15-20 questions right in a row. Since GMAT Math is in a form of CAT (Compute Adaptive Test), the questions get harder if you correctly answer questions, and get easier when you get easy questions wrong. Therefore, after answering the first 7 questions correctly, you can expect your score to be around 35-40. These first few questions will be fairly basic and straightforward. In fact, you will have to keep going for a while, as the questions that are representative of difficulty and score of 50-51 usually appear after a question number 20. Therefore, it is crucial to get the first 20 questions right as otherwise you will not be able to get to hard enough questions to even get a shot at Q50/51.
2. What Concepts/Topics Do I Focus when Targetting Q51 Score?
Overview: It is vital to note in preparation for GMAT Math that Integer Properties, Statistics, Probability, Inequality, and Absolute Value are the most important 5 chapters. Among them, Integer Properties and Statistics are especially important. If you get every question right in “Integer section”, your score can go up as high as 49, and if you get every question right only in “Integer and Statistics section”, you can expect 50 for Math section. Thus, it is vital that you get every key question right from those five areas to score a 51.
Ron, can you explain details about getting Q50 or Q51? also, which chapter i've study more for getting Q50 or Q51, etc?
