For commerce students in India
Learn GST the way you'll be asked to do it.
Not definitions. Not a question bank. You get a stack of invoices, an empty return, and a reviewer who tells you exactly which of your ten checks failed — the same way an articleship would.

GST Registration
Take a new business through Form REG-01 — Part A, TRN, Part B, uploads, a departmental clarification query on REG-03, and GSTIN allotment.
11 steps · a real check digit
GSTR-1 & GSTR-3B
Three businesses, 105 real source documents. Classify every invoice, claim the right credit, and make the cash ledger tie out.
3 case studies · 105 documents
Income Tax Return
ITR-1, ITR-2 and ITR-4. Reconcile Form 26AS, compare the old and new regime side by side, and file the one that actually costs less.
3 scenarios · both regimes
Why it works
Documents first, forms second
Deciding which table an invoice belongs in is the skill. We never autofill it for you.
Ten checks per document
Classification, tax type, and eight typed fields. Partial credit, exactly like a reviewer marking your return.
The chain is real
A mistake in GSTR-1 table 4 becomes a wrong figure in your 3B cash ledger. You feel why accuracy matters.
Read the card first
Fourteen concept cards — one idea, one worked example, and the trap students actually fall into, with the section and the date it was true.
Mistakes are kept
Every check you fail is collected across attempts and grouped by reason, so you can see what keeps catching you out instead of re-reading a list of red rows.
The answers never reach you
Marking happens in the database. The answer key is not in the page, not in the network tab, and not one clever request away.

Questions students actually ask
- Is anything actually filed with the department?
- No. This is a training simulator. It is not connected to the GST portal or the income tax portal, and nothing you submit here reaches any department. The GSTIN you are allotted at the end of the registration module is fictional — it belongs to a made-up company.
- How do I pay, and how long does access last?
- You pay by UPI and paste the transaction reference. Your teacher verifies it by hand and opens your access window — usually the same day. Access is a window with a start and an end, not a lifetime licence, and it can be extended.
- What do I need to run it?
- A laptop. The filing workspace puts the source document and the return side by side, and that needs a real screen — this is not a phone app.
- Are the rates current?
- Every rate, slab and threshold in the product is stated with the date it was true, and the concept cards show it on the card. Tax law moves. Nothing here is tax advice — for a real return, consult a qualified practitioner.
- What happens when my window closes?
- You stop being able to open the modules. Your attempts, scores and mistake notebook are kept, so if your teacher extends or re-opens your access, everything is where you left it.
