Who it is for
Students preparing for the SAT who want practice items and explanations rather than answers to homework.
Overview
ETT supplies SAT practice from a curated question bank rather than generating problems on the spot. The items are written to match the formats and difficulty range of the test itself.
Questions can be pulled by topic, or by similarity to one a student has just worked through, which is how a weak area gets drilled. Section-level practice tests are available for a structured check on progress, and questions come with detailed explanations to review afterwards.
The distinction the developer draws is between a general assistant that answers whatever question is put in front of it and a bank assembled specifically around SAT content. ETT Education and Technology Group publishes the app.
Students preparing for the SAT who want practice items and explanations rather than answers to homework.
Items come from a fixed SAT-aligned bank, and a student can ask for questions similar to one already attempted.
Availability
ETT is listed in the ChatGPT apps directory only. ETT Education & Technology Group has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with ETT Education & Technology Group, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
