The discussion centers on the viability of applying to top 30 PhD programs in engineering with a GPA of 3.3, despite having strong research experience, good GRE scores, and a solid statement of purpose. Participants share mixed opinions on the importance of GPA versus research experience in admissions. One contributor successfully gained admission to a similar program, suggesting that GPA may not be the sole determining factor. The topic of taking additional subject GRE tests in Chemistry and Physics arises, with some advising against it, arguing that it may not significantly enhance the application and could potentially detract from it. Others suggest focusing on research and relevant coursework instead. The conversation also touches on the competitiveness of engineering PhD programs compared to pure science programs and the potential for fellowships like NSF, with uncertainty expressed regarding eligibility and chances. Overall, the consensus leans toward prioritizing research experience and strategic application choices over additional testing.
