About Preptics

Most preparation for a standardised test is a bank of questions and a number at the end. The number says how the sitting went. It does not say what to do tomorrow because of it.

Preptics does the part in between. It keeps a record of every answer, reports where the marks were lost, and rebuilds the study plan from that after every mock, every finished lesson and every set of drills. Lessons, drills and daily missions come out of that plan, so there is always a next thing to do.

The Digital SAT is where we started. The official tools for it do their own jobs well: one administers the test and another teaches the content. Neither tells you what to do tomorrow because of your result.

The numbers are held to the strictest rule we have. A practice score is an estimate, so it is shown as a range with its confidence stated, never as a single figure.

Every method behind those numbers is published, so you can check it rather than take our word for it: how scores work, how questions are made and how the rest of Preptics works.

The Digital SAT is the first track, and it is not all Preptics is for. What does the work underneath is not specific to one exam: an adaptive exam engine, skill estimates built from your answers, review timed for just before you would forget, interactive simulations, a graphing calculator of our own, and a plan that rebuilds itself. It was built as a platform, so the next exam is a new track on it, not a new product.

Where this is going: every standardised test a student sits, as a track in one place, on the web, on a phone and on a tablet, with each new piece of learning technology built once and shared by all of them. We think that is what test preparation becomes, and we intend to be the company that builds it.

We are not there yet. Today Preptics is one track, on the web, made by a very small team. What follows is the order we expect, with no dates, because a date on a page is a promise.

Who writes what

Guides on how scoring and adaptive testing work are written by Md Nasim Sheikh, who built the engine they describe. Guides on the test itself and how to prepare for it are written by Nusrat Tabassum Oyshi, an admission-test instructor who has also reviewed every lesson, practice test and guide on the site. Every guide carries its author's name and the date it last changed, and that date moves only when the words do.

What we check claims against

Facts about the Digital SAT — its timing, structure and scoring — are checked against the College Board's published specifications. Facts about Preptics are checked against the product itself: when a guide says how a number is worked out, that is what the code does.

Where AI is involved

Practice questions are drafted with AI and then pass seven checks, the last of them a person — the full process is on how questions are made. Where AI helps draft or edit a guide, the named author checks every claim in it and answers for the result.

Corrections

If something here is wrong, tell us at support@preptics.com, or use the report button on any question. We fix it and update the page's date, and where a mistake affected anyone's score, the scores it touched are recalculated.

Independence

Preptics is not affiliated with the College Board, and nothing here is endorsed by it. No one pays to appear in a guide, and the site carries no advertising.
