I just published my video explanations to all of the 137 data sufficiency questions that are part of the data insights section in the GMAT Official Guide 2025-2026 that was released at the end of May 2025.
The following data sufficiency questions are new to the GMAT Official Guide 2025-2026: 290, 293, 294, 295, 296, 302, 327, 328, 330, 331, 335, 336, 343, 375, 406, 407, 408, 409. I should also point out that all of these questions have appeared in other official GMAT resources in the past.
