Hi everyone! So I have been preparing for the GMAT FE for a while now, after previously taking the classic exam in January 2023. I realised that I am supposed to take the updated edition of the exam and while I've found answers to some basic queries through search feature, I haven't found satisfactory answers to the following doubts. Any insights you could offer would be incredibly helpful as I'm preparing for the exam on my own. Thanks!

1. Would the OG materials (OG 2022) I used for the previous classic test still be applicable for the FE? I'm aware that Geometry and SC are out, but for the unchanged syllabus, would the old materials still be relevant? Or does the updated exam feature different question types for the same syllabus? Kinda confused on this one.
2. What are some-reliable resources for Data Insights? I came across some informative playlists by GMAT Ninja and GMAT Club on YT for conceptual understanding, but I'm looking for question sets that closely resemble the actual exam. AFAIK, this section relies less on theory or strategies and more on the application of reasoning skills when approaching questions.
3. Has anyone come across a post that breaks down the CAT algorithm for the FE — something similar to the one available for the classic exam maybe? I am not quite obsessed with the algorithm, but it's good to know anyway. From the various posts I've read, there appears to be some inconsistency, and the same was discussed in a recent GMAT Club webinar as well. Has anyone managed to comprehend how exactly that algorithm works?
4. Likewise, has the frequency of topics or question types being asked changed? For instance, the previous test contained more questions from integers, arithmetic, statistics, and geometry. What are some of the common question types or topics that are frequently asked in the FE?
Thanks in advance for the help, cheers!
