What is best approach to clear TX exam with 80+ marks?

Also when September 26 classes will be uploaded?

Lots of question practise!

The notes and lectures that are available now (Finance Act 2025) are good for exams up to and including March 2027.

I have exemptions in Knowledge papers its been while i did my studied those but got exemptions. should i revisit any concepts in FA,MA before starting TX paper or its a standalone paper?

It's a standalone paper really, but you do need to remember your basic FA rules (capital, revenue, P&L).
