Any advice to improve Quant from 47-49 to 50+?
In my opinion, people lag at 47-49 due to the following reasons:
1. At 47-49, you know most concepts well. Perhaps there are some where you know the process but not the actual concept behind it e.g. divisibility - you know how to answer questions based on those but you don't understand what divisibility is so when you get some seemingly tough problem, you are unable to sort it out because your usual process doesn't work. It is important to understand the subtle difference between 'process of solving' and 'knowing exactly why you are following the process'. Say, I know you can solve x^2 - 5x + 6 = 0 in your sleep but why do you take the steps you do? Why do you factorize? Why do you equate each to 0?
Note: I am not saying that you don't know these things. I don't know what you do or don't know. But the problems you have MIGHT be similar.
2. You could be using long winded solutions, making tons of equations and trying to wrap your head around them. Many people love using the mathematical tools and manipulations since it gives them the satisfaction of solving the questions using the 'mathematical; way. But most GMAT questions are not about Math, they are about logic. If you understand the concepts, you can solve most of them in under a minute. It again comes down to 'knowing the concept well'. Try and explore more 'logical and efficient' solutions. I like to discuss concepts on my blog. The link is given below if you want to check it out.
3. Pace yourself properly and don't take it to heart if a question seems beyond reach. Just make an intelligent guess, if possible, and move on. If you fall short of time, you will hurry at the end and that will be disastrous (you will make lots of silly mistakes). Realize, GMAT is a game of wits. If you are at 48 on average, you already have the potential of 51. You just need to keep a cool head, follow the shortest, most logical approach and keep plenty of time at hand.
