r/GRE

r/GRE is the 13th largest of the 14 communities we track in Books, Languages & Learning, with 131.2k members. That is about 0% the size of the niche's biggest community, r/books. Across Nichory's full directory of 363 communities it ranks 355th by member count.

At around 17 years old it is a long-established community. Older subreddits usually have settled rules, active moderation and high trust — but also years of archived posts, so a question that has been asked before will be sent to the search bar. Bring a specific angle.

Its Nichory signal score is 10/10 — our blend of audience size and how fast the community has grown per year. Scores this high mean an active audience that is worth writing for properly.

This community allows promotion only under conditions — typically a designated thread, a participation ratio, or moderator approval. Read the rules first, then either use the thread they provide or write a post that teaches something, with your product as context rather than the headline.
