How checking works

The checker grades your own formula: it recalculates your sheet and compares the result. Hints help when you are stuck.

01

You write a formula

In a spreadsheet that behaves like Excel: the same functions, fill handle, $ and F4.

02

The sheet is recalculated

The trainer computes your formulas in the browser and compares the values with the expected result. Any correct approach passes, not only one template.

03

You get a precise message

If something is off, it tells you where and why, and a hint is one click away. The check runs on your device and nothing is uploaded. AI hints are the exception: they send the task and your formula to our AI provider.

How learning works

A calm rhythm: read, do, and see right away how it went.

01

Short theory

Each concept comes with a small, realistic example.

02

Practice in the sheet

A spreadsheet that works like Excel: formulas, fill handle, $, F4, filters, PivotTables, charts.

03

Instant checking

The trainer recalculates your formulas and explains mistakes. Any correct solution works, not just one template.

04

Real Excel

Download the task file, solve it in Excel and upload it back: the check runs in your browser and the file is never sent anywhere.
