Why students stay

The TuliSir difference

Memorise in class

Concept clarity with an exam-oriented method — students understand and memorise the law within the class itself, not weeks later.

The handwritten charts

A treasure for any CA student — the deepest taxation concepts summarised into the minimum possible content. Revise a whole chapter in one page.

Rank holders, repeatedly

Over 500 All-India Ranks — including the All-India highest scores in both Inter Taxation and CA Final Direct Tax over the years.

Fun while you learn

Lively, interesting classes — the mantra that's defined the TuliSir classroom for over two decades. Tax, but never boring.
