Khan Sir began teaching in Patna with just six students. His simple, humorous way of explaining difficult subjects, often with maps drawn on the board, drew growing numbers of students preparing for government exams such as SSC, railway, defence and state civil services. His institute, Khan GS Research Centre, grew into one of Patna's best-known coaching centres.
In 2019 he launched the Khan GS Research Centre YouTube channel, covering general studies, history, geography, polity and current affairs. Its explainers on news events and geopolitics reached millions of viewers. In 2021 he released the Khan Sir Official app with online courses, which grew into the Khan Global Studies (KGS) platform with separate channels for UPSC, BPSC, SSC, railways, defence and state exams.
In 2025, Khan Sir opened a low-cost hospital in Patna. News reports said it offered tests at very low prices, such as a blood test for ₹7 and an ECG for ₹25, cheaper than many government facilities. He has spoken about plans to open more hospitals, including for cancer care.
