Bablu the calculator waving
BabluHi! I'm Bablu. I ask, you guess, then we check the numbers together.
A story first

Selvi has won an order for 2,000 school uniforms. Every lesson follows that one order, with Ravi’s press, Murugan’s rice mill and Dr. Priya’s clinic joining in.

You try it

Slide, sort and tap. Watch the numbers move before anyone says a technical word.

Then the name

Only after you get it do we give it its proper name, with the line from the standard beside it.

Collect as you go

Every lesson has its own colours, and every lesson you finish presses its own seal in My Ledger. No scores, no grades, no daily targets. Some seals are secret.

Try it in 60 seconds

Course: Cost Accounting Standards

25 lessons in nine stages. They open one by one, in the order that tells the story: start at CAS-1, and each lesson you finish opens the next.

Plain words first, the standard beside it

Each chapter has a “Read the standard” panel: a plain-English summary of the clauses it covers, the version in force, the date we last checked it and a link to the official text on the ICMAI website.

Read the standard · CAS-1 §5.1

In plain words: the same cost can appear in several classifications at once, depending on what the report is for. An electricity bill is an expense, indirect, a production cost and semi-variable, all at the same time.
