I am an IITan. Dr. Rao, qualified GATE with AIR 109, CSIR-UGC with AIR 220, and completed a Ph.D. in Physics from IIT Madras.
My channel "Rao's SciTech" facilitates students to understand concepts of basic sciences which in turn establishes a good viaduct among different technological developments.
This channel is also much useful for all standards of students with State, CBSC, and ICSE syllabi.
