For students navigating the Turkish university entrance system (YKS), there is a dreaded term that strikes fear into the hearts of test-takers: "Broken OBP" (Kırık OBP).
Even if you have a spectacular High School Graduation Score, a single strategic mistake during your university preference (tercih) period can cause your hard-earned diploma points to be slashed entirely in half the following year.
In this article, we will explain exactly what the Broken OBP penalty is, the specific scenarios that trigger it, and the situations where your score is safely preserved.
What is the Broken OBP Penalty?
Under normal circumstances, your High School Graduation Score is multiplied by a coefficient of 0.6 to generate your Secondary Education Success Score (OBP). This OBP is then added to your YKS exam score to determine your final university placement ranking.
However, the Turkish Higher Education Council (YÖK) enforces a strict rule to prevent students from wasting university quotas. If you are placed into a university program through the central placement system in one year, and you decide to retake the YKS the very next year, your OBP multiplier is reduced from 0.6 to 0.3.
This means your diploma's contribution to your exam score is literally halved.
The Math Behind the Penalty
Let's look at the catastrophic impact of a Broken OBP for a student with a solid diploma score of 85.00.
- Normal OBP Contribution:
85.00 x 0.6 = 51 Points - Broken OBP Contribution:
85.00 x 0.3 = 25.5 Points
By simply making a careless university choice the previous year, this student loses 25.5 points. In the highly competitive YKS ranking system, losing 25.5 points is equivalent to dropping by hundreds of thousands of ranks. It forces the student to answer roughly 8 to 9 extra AYT (second stage) questions just to break even with their peers.
Scenarios That TRIGGER the Broken OBP Penalty
Your OBP will be halved (broken) in the following year if you meet any of these conditions:
- You are Placed in a Program: You submitted a university preference list, and the system officially placed you in a 2-year (Associate) or 4-year (Bachelor's) degree program.
- You Placed but Did NOT Register: This is the most common and tragic mistake. Many students think, "I got accepted, but I didn't go to the university to register, so my OBP is safe." FALSE. The moment the ÖSYM system places you into a quota, you have "occupied" that seat. Even if you never set foot on campus, your OBP will be broken next year.
- Open Education Placements: Getting placed in an Open Education (Açıköğretim) program that has a quota limit will also trigger the penalty.
- Special Talent Exams: If you are placed in a university program via a Special Talent Exam (e.g., Fine Arts, Sports Academies), your OBP will be broken if you take the central YKS exam the following year.
Note: The penalty only lasts for one consecutive year. If you were placed in 2023, your OBP is broken for the 2024 YKS. However, if you wait and take the exam in 2025, your OBP will return to normal (0.6).
Scenarios That DO NOT Trigger the Penalty
You can breathe a sigh of relief. Your OBP remains fully intact (0.6 multiplier) in these scenarios:
- You Applied but Were Not Placed: You submitted a preference list, but your scores were too low, and you received the "Not Placed" (Yerleşemediniz) screen. Your OBP is completely safe for next year.
- You Took the Exam but Made No Preferences: You received your YKS scores but decided not to submit a preference list (opting for a gap year). Your OBP is safe.
- Unrestricted Open Education: Registering for an Open Education program via the "Second University Without Exam" right does not affect your YKS OBP.
- Waiting a Year: As mentioned above, taking a one-year gap between the placement and your next YKS attempt resets the penalty.
The Golden Rule of University Preferences
The Broken OBP system teaches a harsh but necessary lesson: Never put a university program on your preference list if you do not genuinely want to study there.
Do not fall into the trap of thinking, "Let me just write something down so I don't feel left out." That fleeting feeling of securing a spot will cost you dearly if you decide to try for a better university next year. Before making any decisions, always use a High School Graduation Score Calculator to understand exactly how many points you stand to lose if your OBP is broken.
