Understanding the GRE scoring system

The first step to increasing your GRE score is to understand the scoring system adopted by the GRE. There are a variety of wrong ideas about how this happens when it really is a simple system to understand.

The GRE is a Computer Adaptive Test or CAT!

So what if it is computer adaptive you may ask. Well, this makes all the difference. In the CAT version of the GRE, the saying "first impression makes the best impression" really holds true. This is because in any computer based test which "adapts", the main objective of the computer is to increase the level of difficulty of the questions until it reaches a level which you find challenging.

So what does this mean for you?

This means that you will only have one attempt to answer a question and then you move on. Unlike a paper based test where you can recheck your answers, in the CAT system your response on the current question will be used to determine the difficulty level of the next and so there is no chance for you to go back and correct your answers. This means you should take utmost care while marking the first few questions.


Let me explain more in depth:

In general the first question in any section is one of medium difficulty. By "medium difficulty" I mean that of any 100 people who attempt this question, fifty would get it right and the other fifty would typically get it wrong.

This means that you will be able to move on to a higher performance level if you get the first question right. In the GRE each question comes from a database of questions. The questions in this database are categorized depending on the percentage of people who get them right on first try. Marks allotment for getting each question right is also predecided by the computer based on the difficulty level of the particular question. If the question you get is considered to be hard then you will be given more marks for getting it right than for getting an easier question right. What this means is that a person who gets his first few questions wrong and then get many questions right (since the difficulty level and hence the marks decrease once you make an initial mistake.) will score much lesser than the person who has answered the first ten odd questions right and then makes a silly mistake. If he has performed well on the first ten to fifteen questions then if he makes a mistake later on the computer will be more forgiving on him and assume that he has made a silly mistake and thus reduce lesser marks for a wrong answer.

This type of question pattern can be plotted on a graph where the curve of the graph needs to be increased from the beginning itself. If this is not done then even if all the remaining questions are answered perfectly you will not be able to score in the high 700's.

Practice is key to making sure you get the first few questions right. Your time management will be tested here since you will have to ensure the correctness of the answers right in the beginning and you shouldn't mess it up. As mentioned earlier I used the Barron's math review chapter to make sure I was up to date with the concepts tested. I found it to be more than enough for my preparation. You will find all the concepts tested in the exam explained in simple language with many sample questions to practice these concepts on.


Making the effort to understand the GRE scoring system perfectly will ensure that you will be able to manipulate it to your advantage and be well on your way to a perfect score.

So How do I improve my performance on the GRE? Read on..

the "hows" is what this blog will deal with.

Improving your performance on the GRE is not a question of mindless hours of preparation. To significantly improve your score you will need strategy as well as knowledge of the inner workings of this important test. I will be totally frank with you regarding the preparation and if my suggestions are followed appropriately it would definitely lead to an increase from your current GRE practice tests score (If it needs any improvement that is..) That being said lets begin in earnest.

STAGES OF PREPARATION:

I would classify the preparation stage into three distinct stages

1. Evaluation

2. Practicing

3. Optimizing


Even though I did not follow such a rigid set of rules during my preparation time, I realized later on that even though my preparation wasn't formal, it followed the sequence given above naturally without me being aware of it. Hence I would advice you to take a note of this structure.

Before You Begin:

1. Make sure you are in a quiet place where you can work undisturbed like the terrace or your room.

2. Get the latest edition of the Barrons GRE book. I found this book to be comprehensive and did not need the use of any other aid to supplement me although my friends did recommend Princeton review, Kaplan and Novapress GRE books to me. Since the GRE mainly tests concepts its essential that you are clear on that and Barron's does a good job in this aspect by having a through math review as well as its renowned 3500 word list which scares most GRE prep'ers away from this book! This word list should definitely be given importance since it seems to have many words commonly scattered around in the examination. However it is also likely that words which do not appear in this list can appear. So a well rounded preparation will help the most imho. Some useful GRE resources can also be accessed.

3. Get a pencil.

4. A stopwatch to time yourself if you have one.

5. A bottle of water.


6. Avoid studying in groups since you will only end up getting disturbed. However you can use the internet and the variety of GRE prep sites and forums to interact with fellow testers to get motivation and to gain more resources to aid you.
