@Cinemaa__ The X thread by @Cinemaa__ claims PhysicsWallah exploits students mentally and misrepresents its student-friendly image. Key points: In 2023, three teachers resigned, alleging a shift from affordable education and poor learning conditions at the Kota center. They denied bribery accusations from another teacher. A viral video showed a student slapping a teacher, and another incident involved a teacher’s outburst. Student reviews are mixed—Trustpilot rates it 4/5, but MouthShut gives 1.8/5 with many complaints. Employee reviews note management issues but praise timely salaries. PhysicsWallah calls teacher exits normal turnover. The debate on quality and culture continues with no clear consensus.
