The discussion highlights the evolution of the Physics Graduate Record Examination (PGRE) since its inception in 1986, focusing on the changes in exam style and content over the years. Participants note that while older exams, particularly those from before the early 1990s, tend to be more challenging, the 2001 exam closely resembles the current format and difficulty level. It is suggested that the 2001 exam serves as a reliable benchmark for gauging the current test's difficulty. Test-takers recount experiences of significant discrepancies between practice exams and the actual test, with some noting that recent exams have not shown a marked increase in difficulty compared to practice materials. Effective test-taking strategies, such as skipping difficult questions, are also emphasized as crucial for achieving better scores.
