Hi
DeOe22,
Firstly, 620 isn't a bad score!
We have had students who have got 570 in their first mock GMAT test and then went on to score a 720.
It's all about figuring out your strengths and recognizing the areas that need improvement.
Here is an 8-week study plan that you could follow:
Week 1 & 2: Work on your Quant & Verbal basics There are a finite number of concepts tested on the GMAT. GMAT is more to do with the applications of theoretical knowledge to everyday problems.
Start by getting yourself familiar with all the concepts tested on the GMAT.
For both Quant and Verbal, go through the Official Guide. These guides have all the theory that you will need to know to ace the GMAT. Make sure you understand these basic concepts well.
You can also
Signup For Our Free GMAT Kickstarter Course. The GMAT Kickstarter course consists of 8+ hours of free GMAT Strategy, concept and application videos. This course will teach you the strategies and techniques required to tackle each of the sections on the GMAT
WEEK 3 & 4: Start working on the Easy and Medium level questions Once you are done learning all the concepts and theory, you will now need to learn to apply these concepts to Original GMAT questions to see how they work.
The three main sources of questions to be used in this phase are as follows:
1. The Official GMAT Guide
2. The GMAT Guide for the Quantitative Review
3. The GMAT Guide for the Verbal Review
When you are solving the questions from these books, make sure that you are learning from your mistakes. You will have to analyze your errors as much as you can so that you do not repeat the same error more than once on any other question.
You could use an
error log to keep track of your mistakes.
Week 5: Take another test.This time, take the second GMAT Prep test full-length to see how your preparation has been working for you.
There has to be a considerable improvement in your score this time. If there isn’t, you will realize that your problem is with the basic concepts – either understanding or application.
Once this test is done, analyze the errors in the test just as you have analyzed the questions in the Official Guides.
If your scores haven’t improved considerably, then you should go over all the theory and go over the questions that you have got wrong in the OG and VR and solve them again to understand the mistakes that you’ve made.
Week 6, 7 & 8: Start working on more questions (The tougher ones!)You will now be at a stage where you have worked out almost a 1000 questions and have taken 2 full-length tests. Post this, the key to effective GMAT preparation is to maintain consistency and the heat to solve questions.
There are three sources of official materials that come handy at this stage.
1. GMAT Prep Exam Pack 1 – This tool gives you two more full-length GMAT Prep tests for $49.99.
2. GMAT Prep Question Pack 1 – This tool gives you access to an additional set of 404 questions to practice.
