FlagshipTaught personally by Dr. Tejaswi
A PhD physicist, an IKS faculty scholar — your personal teacher.
One-on-one coaching in competitive Physics & Mathematics, Sanskrit and scripture, and the classical arts. Dr. Tejaswi teaches with modern tools — live simulations, interactive labs and the writings, the full depth of this website — focused on you alone. More than tutoring — real-life guidance: orienting your study, practice and purpose across all three planes. One hour with a teacher who has lived both worlds saves months of drifting through tabs.
A few intro slots open each week — every session is taught personally by Dr. Tejaswi.
