Hi
aditya1818, agreed with the above that OG questions should be sufficient. You can select the following sources:
OG 2024-25, Data Insight Review 2024-25,
OG 2025-26 and Data Insight Review 2025-26 (Not many new questions though).
Questions tagged GMAT Prep (Classic) and EA are also official questions. Don’t touch GMAT Prep (Focus) in the early stage of your prep, as they are real questions from the 6 official mock exams.
Generally that’s enough DI questions. If you still need more, you can then go for: 1.
GMAT Club Test questions, or 2. Questions from reputable prep companies, such as
Manhattan Prep, Veritas, Kaplan, etc. Those are not official questions though.
