Watch your instructor - Sarfraz - walk you firsthand through the key features of the DI Grail course.
We strongly urge that you watch this video before purchasing the course so you know exactly what you are going to get.
DI Grail isn't retrofitted from older GMAT content. It has been designed from scratch with the GMAT Focus Edition in mind, which means everything you study is relevant, current, and exam-ready.
DI Grail gives you 20 hours of carefully sequenced video lessons across 7 modules, built to take you from foundational understanding to test-day confidence. There's a beginning, a middle, and an end — because random content consumption isn't preparation.
Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, Two-Part Analysis — DI Grail covers all of them with dedicated modules, not passing mentions.
DI Grail comes with 8 months of access. That's intentional. GMAT prep shouldn't become a lifestyle. Eight months is more than enough to master Data Insights, take your test, and move on. We're not interested in keeping you on a treadmill.
Aristotle Prep has been helping serious GMAT students worldwide since 2010. DI Grail is the next evolution of that expertise — now in a format you can access anywhere, at your own pace.
This is complete lesson 9 from the Data Sufficiency module of the DI Grail. Titled "My Tips - 2", this is a question-based lesson in which you'll get a lot of practical tips on what to watch out for on tricky DS questions.
This is complete lesson 2 from the MSR module of the DI Grail. Titled "How to Approach MSR", this a theory based lesson in which you'll be introduced to the strategy for tackling MSR questions effectively. There's also a question discussion from 17:13:00 onwards.
When the GMAT Focus Edition (now simply called the GMAT) launched in 2023, it didn't just add a new section in Data Insights. It fundamentally changed what test-takers need to master. Data Insights combines graph interpretation, multi-source reasoning, data sufficiency, and two-part analysis in ways that reward structured thinking — not guesswork or last-minute cramming.
Every major test prep company has a DI module. Almost none of them built their course around DI. We did. DI Grail was built from scratch — not adapted from old material, not recycled from a broader GMAT course. Every lesson, every example, every practice set was designed with one question in mind: what does a student need to go from confused to confident on this section?
This course is for you if:
I’ve only completed the first three modules of the DI Grail, but it has already changed how I approach Data Sufficiency questions. I had a tendency to overthink DS questions and spend too much time on those. Sarfraz’s pre-thinking strategy for DS has been a game changer for me.
- The content is crisp and to-the-point.
- Sarfraz’s teaching style is engaging and very easy to understand
- Tons of practical insights, especially with regards to guessing, eliminating, approximating, etc.
I’m still going through the DI Grail, but what I like the most so far is Sarfraz sir’s approach to tackling questions, which is very different from what I had been taught earlier. He speaks a lot about “efficiency” while answering questions, and I feel like I’m reading questions like him whenever I practice now.
Please reach us at support@aristotleprep.com if you cannot find the answer to your question. And do watch Sarfraz's video (scroll up) and you'll get answers to pretty much every question you have, inlcuding some you may not even have thought of.
The course is valid till 8 months from the date of enrolment. We've made this a deliberate choice — GMAT prep shouldn't stretch into years. 8 months is more than enough time to master Data Insights, take your test, and move forward. We're not here to keep you subscribed indefinitely. The duration can, of course, be extended in special cases. We are good people.
DI Grail is built exclusively for the GMAT Focus Edition, which is now simply called the GMAT. The old format (Classic version) of the test isn't offered anymore, in any case.
Absolutely. Aristotle Prep has always been a global operation — a majority of our 7,500+ students are based outside India, primarily in the US. The course is in English, payment works in both INR and USD, and all content is accessible worldwide.
We offer a 7-day refund for students who feel the course isn't the right fit — provided you've completed less than 20% of the content. We strongly encourage you to watch the free sample lessons before enrolling, so you know exactly what you're signing up for.
Most GMAT courses treat DI as one section among three. DI Grail treats it as the entire subject. Every lesson, example, and strategy was designed specifically for Data Insights — not adapted from older material or bolted onto a broader course
Not currently. DI Grail is fully self-paced. We're evaluating live components for future course versions. But there will be discussion threads below each lesson where Sarfraz will personally respond to your queries.
No. And that's by design.
We strongly believe that the only practice questions you should be using for GMAT preparation are the official questions published by the GMAC. This is especially true for Data Insights, where poorly designed unofficial questions can do more harm than good by reinforcing incorrect approaches and creating confusion about how the exam actually works. In fact, we've intentionally offered you a discount on the course because we'd rather have you invest that money in purchasing official GMAT questions and materials.
That said, the course is far from theoretical. Throughout the program, we'll be discussing and analyzing more than 100 official GMAT Data Insights questions in detail. You'll learn the underlying concepts, strategies, and thought processes while working through a large number of authentic exam questions.
The course is delivered entirely through pre-recorded video lessons that you can watch at your own pace. There are no fixed class timings, allowing you to fit the course around your work, studies, and other commitments.
Whether you prefer to complete the course in a few weeks or spread it out over several months, you'll have the flexibility to learn according to your own schedule. You can pause, rewind, and revisit lessons as often as needed, making it easy to reinforce concepts and review challenging topics before test day.
The course can be accessed simultaneously from three different devices.
Yes you can by logging on to our learning management system weblink through your mobile device. However, to make things even smoother, we are in the process of developing a proprietary app using which you can access the course on your mobile device. We expect the app to be ready by September/October 2026.
We accept all payment methods supported by Razorpay in India, including credit cards, debit cards, UPI, net banking, wallets, and EMI options (where available).
We also accept international payments, so students from outside India can pay using internationally issued credit and debit cards, making it easy to enrol from anywhere in the world.
All payments are processed securely through Razorpay's encrypted payment gateway.
Access is granted immediately after your payment is successfully processed. In most cases, you'll be able to start the course within minutes of completing your purchase.
We offer a 7-day refund for students who feel the course is not the right fit, provided that less than 20% of the course content has been completed.
To request a refund, please email us within 7 days of purchase using the email address associated with your enrolment. Include your name and payment details so we can locate your order.
Course completion will be determined based on the learning platform's progress-tracking data, which will be used to assess refund eligibility.
Once a refund is approved, your access to the course will be revoked and the refund will be processed within 7 business days. The time taken for the funds to appear in your account may vary depending on your bank or payment provider.
We strongly encourage students to review the free sample lessons before enroling so they can make an informed decision about whether the course is right for them.

If Data Insights is holding your GMAT score back, it's not because you're not smart enough. It's because nobody has taught you how to approach it properly.
DI Grail changes that.
