Yes. Sentence Correction is the biggest new content area if you have been preparing for the current GMAT, but I would not assume that GMAT preparation alone makes you fully EA-ready.
There is substantial overlap. EA Verbal includes Reading Comprehension, Critical Reasoning, and Sentence Correction. EA Quant includes Problem Solving and Data Sufficiency, and the Integrated Reasoning section includes Multi-Source Reasoning, Graphics Interpretation, Two-Part Analysis, and Table Analysis.
So, beyond learning Sentence Correction, I would spend some time getting accustomed specifically to the EA format, particularly its Integrated Reasoning questions, Data Sufficiency in the Quant section, pacing, and the EA’s module structure. The EA gives you 30 minutes for each of its three sections, and each section is divided into two modules. You can review and change answers within a module before moving on, which makes the testing strategy somewhat different from the GMAT.
The good news is that after three months of solid GMAT preparation, you should already have a substantial portion of the underlying skills you need. I’d learn Sentence Correction thoroughly, do some EA-specific practice to identify any gaps, and then spend enough time with official EA questions and practice tests to become comfortable with the format and timing.
Good luck!
