Hi
Yudhajit22,
GMAT Ninja may give you advice on how to tweak the study plan, so I'll just answer your second question.
Imo, you don't need to buy the OG 2025-2026 bundle. At most, get the main OG. This is primarily to get the DI questions in the main book, which are different from those in the separate DI review guide you already own, and practice on the official interface through the online question bank on mba.com. After all, it's the official DI questions that are in short supply.
For Quant and Verbal questions, I think you can just use GMAT Club forums to get more questions. Questions in these two sections have not changed much for years so there is abundant inventory from the past. In source filter, you can pick all the OG and Quant/Verbal review guides all the way back to OG 12 and Quant/Verbal Review Guides 2nd Edition. That should give you a lot more official questions than just the 2025-2026 Edition.
If you are looking for questions at a harder level, you can also use the source tag "GMAT Prep (Classic)". These questions are from previous edition of official mock tests, and are generally considered to be a bit harder than the OG questions. Also don't forget, one feature of this study plan is to leverage LSAT resources to sharpen your RC/CR skills.
In summary, I'd say save the money on the 2025-2026 bundle, and use the money to invest in potentially further DI questions in the official practice question pack, or some sectional tests that you may need down the road.

Hello , I’m about to begin the GMAT Ninja study plan, but I have a few questions before getting started.
I’ve already taken the official GMAT in 2025 and scored 605. My target score is 695+.
Do you have any suggestions on how I can tweak this study plan to maximize my improvement? My weaker areas are Data Insights and Verbal.
Additionally, I already own the GMATTM Official Guide 2025–2026 Data Insights Review (online question bank), the hard copy of the Official Quant Review, and the Official Verbal Review 2022. However, I’ve already worked through most of these questions and remember many of them.
Given that, would it still make sense to purchase the GMAT Official Guide 2025–2026 bundle (eBook + online question bank)?
