What is in the Roman numerals kit?

10 questions made by rule with fresh numbers every time it is opened, each with an explanation. Both ways, up to 2,000: the numeral to the number, and the number to the numeral.

Does it cost anything?

A free account opens every kit. Procto AI’s writing runs on a monthly allowance that the free plan includes; a children’s kit uses none of it, because its questions are made by rule.

What happens after the quiz?

The study screen shows the answer and the explanation after each question, then the questions missed, and offers a retry of those. Come back in a few days and take it again: what is still right then is what is known.

About this kit.

Both ways, up to 2,000: the numeral to the number, and the number to the numeral.

What the history, geography and religion kits are

History with dates in order and sources judged, geography with maps clicked and regions outlined, religious studies with texts and their claims. Rule kits for capitals, dates, flags and the sequence of events; material kits from your own textbook.

Why they are built this way

The humanities are about sequence, place and argument. A timeline shape tests the order of events better than any multiple choice; a map shape tests where; a source question tests judgement. These kits use those shapes, so a history student is tested as a historian is.

How to use them

Use the timeline and map kits for the backbone facts and the material kits for the course's own arguments. For essays, the defend-a-position shape with a rubric.

Made by rule

This kit is made in code: every time it opens, the numbers, words or arrangements are drawn fresh from its rule, so the same kit taken twice is two different quizzes from one rule. There is no answer bank to find, and the practice never runs out. Each question carries its explanation, shown at once in study mode.

The shape: maths expression

An equation or expression typed and checked: algebra, calculus and any answer that is a formula rather than a number.

Expressions, numbers and single-form answers are marked by rule, with tolerances and half-credit tolerances where you set them. A typed expression or chemical equation is compared sign for sign, with spacing ignored, so each form you accept is listed, and a slip that would be forgiven in a word is never forgiven here; working and code are marked by a reader against your rubric, step by step.

Taking it

Open it in study mode for the answer and the explanation after each question, and a retry of only what you missed. Switch to exam mode for the real conditions. It comes due again in a few days; the dashboard shows what is due and what you missed last time. Share it with a code for a class, print it as a paper, or host it on a screen for a room.
