The Shocking Impact of High School GPA on the 2026 Turkish University Entrance Exam (YKS) Rank

With the conclusion of the 2026 Turkish Higher Education Institutions Examination (YKS) marathon, all eyes are now on how final rankings are calculated. According to analyses published by reputable educational media outlets, including GZT, the secondary education success score, abbreviated as OBP, is playing a more decisive role than ever this year. This score, derived directly from the candidate's high school GPA, can create massive differences in the final ranking [1].

A 40,000-Place Drop Lurking for Top Candidates One of the most concerning aspects of this year's exam is the inverse impact of GPA on ranks below 100,000. According to statistical data, a candidate ranked 100,000 based on their written exam score may drop to a rank of 140,000 after the OBP score is applied if they have a low high school GPA [1]. This 40,000-place shift means many students might lose their chance of admission to their preferred programs at top state universities solely due to their high school grades.

OBP Calculation Mechanism in 2026 The Measuring, Selection and Placement Center (ÖSYM) calculates the OBP score by multiplying the high school GPA (on a 100-point scale) by 5, resulting in a value between 250 and 500. This number is then multiplied by a coefficient of 0.12 and added to the exam score [2]. In the intense competition of 2026, even a one-point difference in GPA can lead to thousands of people shifting in the ranking list. Education experts believe that in recent years, due to the increased difficulty level of questions, the impact of academic records in differentiating candidates of the same level has significantly increased [3].

Why This Is Vital for Candidates Many candidates focus only on their performance on exam day, but the reality of YKS 2026 shows that success in this exam is a four-year process. Analysts warn that candidates should not rely solely on their raw rank during the preference (Tercih) period but should base their decisions on the OBP-adjusted rank [1]. This 40,000-rank gap demonstrates the importance of balance between school grades and national exam performance, which can be the boundary between admission to medicine or engineering versus other fields.
