I wanted some feedback regarding GMAT Focus Data Sufficiency.

I understand that the underlying concepts tested are essentially the same as in the classic version, but the questions now seem more word-heavy and narrative-driven rather than being presented in a more direct mathematical format.

While the Official Guide remains a great source, would you still recommend practicing DS questions from the classic GMAT as well, including older Manhattan and Veritas questions?

Also, I noticed there do not seem to be many non-math-based DS questions available. What would you recommend as good sources for practicing those?

Hi  Usernamevisible ,

Happy to help!

For DS questions, right, you could still solve questions from Classic GMAT, but make sure, like you mentioned, you practice word problems only, and not the direct and pure math questions. It can still be a great source.

For non-math DS, yeah, unfortunately, we don't have many questions from OG, which is why you have to use them wisely.
I personally haven't practiced much from non-official questions for non-math DS. I am hoping others will pitch in their suggestions on this one.

All the best!

Usernamevisible, really good questions here. I prepped heavily on DS Focus Edition so let me share what actually worked.

On your first question: yes, classic GMAT DS is still worth doing, but with a filter. The older questions that are purely algebraic, like "is x positive?" with two pure inequality statements, don't show up much anymore. What you should be mining from older material is the word-problem DS, the ones with overlapping sets, rates, percents, ratios. Those translate almost perfectly to GMAT Focus Edition style. Manhattan GMAT's DS questions in their Strategy Guides are solid for this.

On non-math DS: this is genuinely thin territory. There aren't many good non-official sources. What I did during my prep was use GMAT Official Guide question sets and the GMAT Focus Official Starter Kit, then filter specifically for DS questions tagged "statistics" or "logical reasoning" types. For non-math DS practice, the GMAT Club question bank actually has a category filter for Data Sufficiency with tags like "word problems" and "other." That's probably your best bet outside of official material.

One thing that helped me a lot: for each non-math DS question you attempt, practice writing out in one sentence exactly what information would be sufficient to answer it. GMAT Focus Edition DS rewards people who can articulate the sufficiency condition clearly before they evaluate the statements. That habit transfers to trickier logic-based questions.

Good luck with your prep.

When the test-makers recently created the Focus version of the GMAT, they changed the type of Data Sufficiency (DS) questions asked. Previously, most DS questions consisted of purely mathematical setups (e.g., the question asks “What is the value of x?,” and the two statements consist of equations that may or may not be solvable for x). On the current GMAT (GMAT Focus), DS is part of the Data Insights section, alongside Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis. Now, DI is designed to test reasoning under real-world, data-rich, often narrative-driven scenarios. That is why the DS questions you are seeing feel more word-heavy and less like the clean, formula-first prompts from older material. 
 
So to your direct question: yes, working older Data Sufficiency questions from the classic GMAT is useful, but with a specific purpose. Those older questions are good for drilling the sufficiency reasoning itself: identifying what the question is really asking, evaluating each statement independently before combining them, watching out for the classic traps like assuming integers, forgetting negative values, or sliding past zero. That reasoning skill is durable, and older DS material trains it well.

What older material won't give you is exposure to the way DS now lives inside a broader Data Insights skillset. The wordier setups, the scenario framing, and the closer relationship between DS and the other DI question types all reflect the current test, and the only way to build comfort with them is with up-to-date resources.

Hi Usernamevisible,

I've taken the GMAT 4 times (3 old format, 1 current). If anything, the new GMAT has more direct math questions (because of math DS). The DI section is basically IR (old GMAT) + DS (math & non-math).

That's not to say that you don't have a point. I thought that the DI questions were generally not as good as those on the old GMAT, but that could just be the small sample size.
