Who writes this

Everything published on GMAT GRE Prep carries one byline: Devin Marsh. That is a masthead name, not a résumé, and this page explains exactly what it does and does not stand for.

The byline is a working name

Devin Marsh is the name this site publishes under. It is a working name, used so that every guide, practice question, and correction on the site answers to a single consistent editor rather than an anonymous house voice. It is not a claim about a specific individual's degrees, employers, test scores, or career, and you will not find an invented biography or a stock portrait attached to it here. Where credibility on this site comes from, it comes from sourcing you can check, not from a byline you cannot.

What the role actually covers

The byline is a description of process. Four things sit behind it:

  • Sourcing. Every factual claim about either exam is taken from the official publishers, mba.com for the GMAT and ets.org for the GRE, and not from other prep sites or forum posts.
  • Checking. Practice questions are solved a second time from scratch before publication, so that exactly one answer choice survives and the stem is not ambiguous. Nothing is published unread.
  • Updating. Exam-format pages are re-read against the official sources on a schedule, and immediately when GMAC or ETS changes a test. A page's updated date moves when the page was genuinely checked.
  • Answering corrections. Reader reports come to one desk and jump the queue, including the ones that end in a disagreement.

The full version of all four, including what this site refuses to claim and how it is funded, is on the editorial standards page.

Hold the byline to something

A byline is only worth anything if you can make it answer for a mistake. If a practice answer is wrong, an exam detail is stale, or an explanation does not survive contact with the actual test, send the page URL and the problem to[email protected]. That address reaches the same desk that wrote the page, not a support queue.
