The Ultimate Guide to GMAT Self-Study: What You Really Need
Preparing for the GMAT can feel like an overwhelming task, especially with the plethora of study materials available both online and in print. However, I’m here to tell you that you don’t need to break the bank or drown in a sea of textbooks to achieve a high score. In fact, I believe that many of the resources you think you need are unnecessary. In this article, I’ll share the essentials that helped me achieve a 760 score, and I’ll explain why you might not need those expensive books or tutoring sessions.
Your Most Valuable Resource: Personal Notes
First and foremost, your own notes are your most valuable study material. The GMAT tests a wide range of subjects, and everyone has their own personal blind spots. As you encounter problems—especially those you can’t solve immediately—make detailed notes. Generalize the problem and outline a step-by-step plan to tackle similar questions in the future. Over time, this will help you build a comprehensive personal guide that you can refer to when approaching certain types of questions.
To make the most out of your notes, it’s crucial to keep careful track of your mistakes and update your notebook regularly as you progress. This practice not only reinforces your learning but also helps you identify patterns in the types of questions you struggle with.
Quality Exercises: The Key to Success
When I started my GMAT journey, I mistakenly thought I needed to buy GMAT books to access quality questions. However, I soon discovered that the GMAT Club offers a database filled with free GMAT exercises. Once you create an account, you gain access to a comprehensive table of contents that allows you to filter exercises by type and difficulty level. Each question comes with expert explanations, giving you insights into the underlying theory at no cost.
The benefit of using GMAT Club questions is that they have been explained by multiple GMAT masters. This variety allows you to learn the general tricks behind questions that you find challenging. By utilizing this resource, you can save money while still getting high-quality practice.
The Importance of Mock Tests
While having access to a wide range of questions is fantastic, it’s essential to simulate the test environment as closely as possible. Quality mock tests are crucial for your preparation. The GMAC, the publisher of the GMAT, offers two free mock tests that are perfect for establishing an initial baseline and for final preparation. You can also purchase additional mock tests, which are of excellent quality, although they may lack some detailed analysis features.
One option that satisfies all analysis needs is the mock tests provided by Active Prep. However, be aware that these tests are bundled with less useful books, which may not be ideal. On the other hand, Manhattan Prep’s mock tests allow you to take the test multiple times due to the adaptive nature of the GMAT Focus. If you perform poorly the first time, the second attempt will present you with higher-level questions, making it feel like a different test altogether.
Additionally, don’t overlook free mock tests offered by various course providers, universities, or even local institutions. For example, my home university, HEC Paris, sometimes offers free mock tests. It’s worth exploring these options to find valuable resources.
Utilizing YouTube for Theory and Strategies
When it comes to understanding the theory behind GMAT questions, YouTube is a treasure trove of free, high-quality explanation videos. Channels like GMAT Ninja and Wizako GMAT Prep provide valuable content, ranging from live mock test solving to theory explanations and test-taking strategies. Personally, I found GMAT Ninja’s playlists on Quant and Verbal particularly helpful.
However, be cautious as some videos may cover outdated content. A quick YouTube search can yield helpful results, especially if you’re struggling with a specific issue. For instance, typing “GMAT explanation video” into the search bar can lead you to multiple high-quality resources that can help you learn advanced GMAT tricks in no time.
What You Don’t Need
Now, let’s address the elephant in the room: what you really don’t need. While GMAT books, online courses, and private tutoring can be beneficial for certain types of students, they often come with hefty price tags that don’t add much value for the majority of test-takers.
GMAT books tend to provide basic theory and practice questions that you likely already know from high school or university. Instead, I firmly believe that the GMAT Club database, with its extensive collection of questions and explanations, offers better resources for free. Online courses, while structured, are not necessary for most students who can plan their studies independently.
Private tutoring is the most expensive option and should only be considered if you’re completely stuck or under severe time pressure. In most cases, it’s not a guarantee of success, and I would advise against it unless absolutely necessary.
Summarizing Key Points
To summarize what we’ve discussed so far:
- Make Good Notes: 80% of your studies should focus on creating detailed notes and generalizing explanations for every question you get wrong.
- Use GMAT Club: Utilize the GMAT Club database for all the exercises you’ll ever need. This resource is also great for theory.
- Watch YouTube: Leverage YouTube for quality explanations on specific subjects if you struggle with certain topics.
- Skip the Books: If you have a decent foundation in high school and university mathematics, you likely won’t need basic GMAT books.
- Avoid Expensive Courses: Courses can be costly and often add little extra value.
How to Use the GMAT Club Database Effectively
Now, let’s dive into how I used the GMAT Club database to achieve a high score. First, you’ll need to register for a free account on GMAT Club. Once you’re in, you can explore various sections, including Data Insights, Critical Reasoning, Reading Comprehension, and Problem Solving.
For example, if you want to focus on problem-solving questions, you can filter by difficulty level. This allows you to tailor your practice to your specific needs. Once you select your criteria, you’ll see a list of relevant questions, complete with timers and answer options. If you get a question wrong, you can access explanations and compare different approaches from other users.
Playing around with the GMAT Club Navigator is a great way to familiarize yourself with the platform and find the resources that work best for you. I also highly recommend checking out the GMAT Ninja playlists, as they provide a solid foundation for approaching GMAT questions effectively.
🧠 Final Thoughts
I understand that preparing for the GMAT can be stressful, and you might be tempted to invest in expensive courses or tutoring sessions. However, I strongly encourage you to take a step back and realize that studying for the GMAT Focus doesn’t have to be complicated. With the right guidance and resources, you can navigate your preparation successfully.
To help you get started, I’ve written free articles that guide you from the initial phase of studying to the final moments before taking the test. Everything is completely free, and I’m not affiliated with any book or course provider, so you can trust that this advice is unbiased.
