Revising the chapter the exam is on

The problem

Why does revision usually cover too much?

"Homework is a daily fight" is one of the eight problems a parent can pick on the first screen after installing Reward Study, and the version of it that shows up the night before a science test is a specific one. A child says the test on Friday covers force and acceleration. What actually lands in front of them to practice, from most worksheet packs and most apps, is a quiz on physics in general, or on science in general, when only one chapter is going to be marked.

Half of that practice is wasted on chapters that will not be tested for months. It also teaches something worse than wasted time: that revision and the actual test are two unrelated things, one broad and one specific, and a child has to do the sorting themselves to work out which twenty minutes of practice actually mattered. That is the opposite of what a task with a clear price and a clear outcome is supposed to feel like everywhere else in the app.

It shows up in ordinary ways too. A pile of downloaded science worksheets covers ecosystems, magnets, the water cycle and cells, whatever a website decided to bundle together that week. None of it is wrong to know, but on the Thursday before a test on pressure, none of it is what a ten-year-old needs either, and sorting a stack of unrelated worksheets for the one page that matters is its own kind of homework fight, on top of the original one.

The child's side

Nobody wants to practice everything to prepare for one thing

From the child's side this is a scale problem more than an accuracy problem. A child nervous about a test on the senses does not need a refresher on animal groups or how a plant makes its own food at the same time. They need the senses: the actual terms, repeated until they stop feeling unfamiliar, in the twenty minutes before dinner when revision is actually going to happen. A generator that hands back a mixed set covering the whole of Biology is handing a nervous child an extra job, working out which of the questions in front of them are the ones that matter for Friday, on top of the job of answering them.

This is where separate science areas do something a broad mixed quiz cannot: they let a child feel finished. Ten questions on the senses, all correctly answered, is a complete unit a child can point to and say they know it, in a way that ten questions scattered across seven different areas of Biology never quite is. For a child who gets anxious before tests, that feeling of having covered the actual ground matters more than the number of questions attempted.

What the app does

Four subjects, and only one is built from packs

The study generator behind Reward Study's practice sets covers four subjects: Math, Physics, Chemistry and Biology. Math is organized into four packs, Math Basics, Fractions and Decimals, Shapes and Measures, and Pre-Algebra, spread across 19 topics with three age bands each. Physics, Chemistry and Biology are not built as packs at all. Each is a flat list of chapter-sized areas, and a parent picks the area directly rather than a pack that bundles several chapters together.

• Physics, 7 areas, from age 12: Speed and distance, Weight and gravity, Pressure, Levers and balance, Force and acceleration, Work energy and power, Density.
• Chemistry, 5 areas, from age 12: Counting atoms, Balancing equations, Relative formula mass, Element symbols, Counting with a number in front.
• Biology, 7 areas, from age 8: Animal groups, The senses, Parts of a plant, Organs of the body, Parts of a cell, How plants make food, Food chains.

That is 19 areas in total across the three sciences, the same count as Math's 19 topics, organized differently. There is no separate ecology subject in the app: food chains live inside Biology, next to the senses and how a plant makes its own food, the same place a school textbook puts them.

What it is not

A generator is practice, not a lesson

It is worth being honest about the limit here. The generator does not teach the idea behind a chapter, it produces a set of questions on that chapter and checks the answers against it. A child who has never met the idea of density will not learn what density means from twenty density questions in a row. What the generator is actually good for is repetition once a concept has already been taught, at school or from a book, in the narrow window when a specific chapter matters more than the whole subject around it, which is exactly the night before a test on it.

Why chapters, not subjects

The reasoning behind picking a chapter, not a subject

The reasoning behind the whole structure is straightforward once it is said plainly. A test is never really about 'science': it is about one chapter of it, so the revision generated the night before should match the chapter, not the wider subject the chapter happens to sit inside. Splitting Physics, Chemistry and Biology into 19 separate areas is what makes that possible. A parent picks the chapter being tested, generates a set on it, and nothing else is mixed in.

The same generator covers the numbers side of homework in the four Math packs, described in how homework becomes a task. Between the sciences and the Math packs, a parent can cover a Tuesday test on levers and a Thursday test on fractions from the same screen, priced in credits like any other task in the household.

Generating a new study set is one of the things that pauses if a subscription lapses; a set already assigned stays visible and gradable regardless. See what Pro includes before choosing a plan for a household with more than one subject to get through before report cards.
