The discussion centers on preparing for the GRE while aiming for admission to top universities, particularly in physics. The original poster, a master's student at IIT Bombay with a high CPI, seeks guidance on the GRE scores needed for competitive applications to top 20 and top 10 universities, specifically MIT. While no specific GRE scores guarantee admission, it is suggested that a general score of at least 2100/2400 and a subject score of around 800/990 would be competitive. However, the importance of strong recommendation letters and research experience is emphasized. There is also a correction regarding MIT's GRE requirements, clarifying that the physics department does require GRE scores, contrary to a previous claim that it does not. Additionally, a tool for estimating admission chances is recommended.
