Payal Tandon
Co-Founder, PRiSM Learning · Co-Founder, e-GMAT
Payal is the #1 GMAT instructor worldwide — co-founder of
e-GMAT, the world's most-watched GMAT prep platform and the
company behind more 700+ scorers from India than any other prep
brand. Over the last 18 years, she's built the teaching
practice used by 100,000+ students across 50+ countries —
pioneering the closed-loop, first-principles pedagogy that PRiSM
is built on.
With PRiSM, Payal has rebuilt that methodology for the Digital SAT
Math section. Same founder, same closed-loop pedagogy —
concept-first teaching, rolling-average mastery, root-cause review
— retuned for the 1600 scale and the way the College Board
actually tests quant.
"
We don't believe in tricks. We've taught quant from
first principles for two decades — what each
formula means, where it breaks, how to reason it out on test day.
The SAT Math section rewards exactly that.
