Wait, if I walked 4 m north and 4 m south, isn't that 8 m total?
That is exactly 8 m of distance, the path you took. But displacement only cares about where you started vs where you landed.
So if I end where I started, displacement is 0?
Yes. The quick check catches this kind of mix-up before the lesson moves into graphs and formulas.

Quick answers before you start.

Will this help me for school exams?

Yes. Each chapter teaches one idea at a time, then checks the graph, formula, or misconception pattern students usually miss.

What if I already know some parts?

The 3-question check can skip safer basics and start later in the chapter. Your first lesson should not waste time on what is already clear.

Is it free? Do I need to log in?

The first run does not need a login. Signing in is only for saving progress, reports, and revision work across devices.

What happens after the report?

You get focus areas, next steps, a chapter notebook for revision, and report PDF actions for saving or sharing with a parent or teacher.

Which chapters are live right now?

The chapter library shows only chapters that are ready to study. Pick any visible chapter and PrepNudge will start with a quick check.

Can parents or teachers use it?

Yes. The report is meant to show what is strong, what needs practice, and what the student should do next without reading the whole lesson.
