Student mistake & performance insights
Marks don't tell the whole story.
Instead of 'work harder in Physics', CoachOne shows teachers where students stumble, finds gaps from earlier classes, and suggests the revision to run in tomorrow's lecture.
Every screen on this page is the live product.
Pinpoint batch weaknesses before the final exam
A score of 52 out of 100 doesn't tell a teacher what to re-teach. CoachOne maps performance across chapters and question types so the next lecture starts where the batch is weakest.

Why students pick the wrong option
A wrong answer is rarely random. CoachOne sorts MCQ mistakes by cause, so a teacher can tell a sign slip from a concept gap.
Sign convention slips
A forgotten negative sign in Lenz's law, or mirrored coordinates in ray optics.
Formula input errors
Diameter used for radius, or peak voltage confused with RMS.
Concept confusion
Adiabatic treated as isothermal, or series capacitors mixed up with parallel.
Unit and magnitude slips
A missed cm to m conversion, or energy left in eV instead of joules.
Find the root cause in earlier classes
When a Class 12 student struggles with alternating current, the gap is often in Class 11 oscillations. The tracer follows the chain back so teachers fix the real problem.
- Prerequisite tracing: Links a Class 12 chapter to the Class 11 topic it depends on.
- Foundation health: Shows which earlier topics are weak across the batch.
- A 10-minute refresher: Sends a short revision for the weak prerequisite, before the chapter is re-taught.
Students see where each mark went, too
The same engine that marks your batch's answer sheets gives every student a step-by-step breakdown and a report card on their phone in the PrepOne app, so feedback reaches them without a teacher writing it.
- Step marks: marks for the law, the formula, the working and the final answer, each explained.
- Report card: correct, wrong and skipped counts, performance by difficulty, and strong and weak topics.
Parents hear from you the same evening
