Introduction
The university preference period in Turkey is filled with excitement, but it also carries hidden risks. Sometimes, students hastily apply to departments they aren't truly passionate about, thinking, "I'll just list it to be safe." However, if they get placed and later decide they want to retake the exam the following year, they face one of the strictest rules in the Turkish higher education system: the Broken OBP (School Success Score Penalty).
The Turkish measuring, selection, and placement center (ÖSYM) applies this deterrent rule to ensure fair placements and prevent university quotas from remaining empty. If you were placed in a higher education program through the YKS the previous year and you take the exam again this year, the contribution of your high school diploma grade to your final placement score will be slashed by half.
In this article, we will delve into exactly what the Broken OBP is, who it applies to, the mathematical coefficients behind the system, and how to calculate that terrifying point drop using our Okul Başarı Puanı (OBP) tool.
What is Broken OBP (OBP Penalty)?
Under normal circumstances, your high school diploma grade is mathematically converted into the OBP and added to your raw university entrance exam score. However, according to ÖSYM regulations, candidates who were placed in a higher education program (including those via direct transition without an exam) the previous year will face a 50% reduction in their OBP contribution if they retake the exam the following year.
The underlying philosophy is simple: When a student secures a spot in a university program but fails to enroll—or enrolls and drops out immediately—they are essentially taking a seat that another dedicated student could have utilized. To prevent this waste of educational resources, the system penalizes the student the following year by cutting their high school bonus points in half.
Who Does the Broken OBP Apply To?
The OBP penalty is APPLIED if:
- You were placed in a bachelor's (4-year) or associate degree (2-year) program based on your YKS preferences last year. (It does not matter whether you actually registered at the university; merely being "placed" triggers the penalty.)
- You registered for a program that accepts students via special talent exams last year.
- You were placed in open education (distance learning) quotas.
The OBP penalty is NOT APPLIED if:
- You submitted a preference list but were not placed anywhere.
- You took the exam, passed the threshold, but chose not to submit a preference list at all.
- You failed the special talent exams.
- The program you were placed in was subsequently shut down by the state.
- Two or more years have passed since your placement. (For example, if you were placed in the 2023 YKS and retake the exam in 2024, your OBP is broken. But if you wait until the 2025 YKS to retake it, your OBP will return to normal. The penalty only lasts for one subsequent exam cycle.)
The Broken OBP Formula and Calculation
The backend logic of our School Success Score calculator utilizes specific parameters to compute this penalty accurately. Let's look at the math.
In a normal calculation, the final added points are determined by:
`Normal OBP Contribution = Diploma Grade * OBP Multiplier (5) * Placement Coefficient (0.12)`
However, if a student is subject to the Broken OBP penalty, a new variable enters the formula: the Broken OBP Coefficient. The standard penalty coefficient set by ÖSYM is 0.5 (a 50% reduction).
The formula then becomes:
`Final Placement Contribution = Normal OBP Contribution * Broken OBP Coefficient (0.5)`
Calculating the Point Drop: An Example
Let’s assume you have an excellent diploma grade of 90. Under normal circumstances, this would provide a massive boost to your ranking. However, last year, you were placed in a department you didn't really want, and you are retaking the exam this year.
Step 1: Finding the Normal Contribution
- OBP = 90 * 5 = 450
- Normal OBP Contribution = 450 * 0.12 = 54 Points (This was the bonus you received last year).
Step 2: Applying the Broken OBP Penalty
- Final Placement Contribution = 54 * 0.5 = 27 Points
Step 3: Calculating the Loss (The Deduction)
- `Deduction = Normal OBP Contribution - Final Placement Contribution`
- Deduction = 54 - 27 = 27 Points Lost
As you can see, a student with a 90 diploma grade loses exactly 27 points due to the Broken OBP penalty. In the highly competitive YKS rankings, losing 27 points usually means falling tens of thousands of places behind your peers.
Is It Logical to Take the Exam with a Broken OBP? (Case Analysis)
Many students ask, "Rather than studying in a department I hate, can I still win a spot in a top-tier Medical or Law school despite the Broken OBP?"
Mathematically, the Broken OBP is a massive hurdle, but it is not impossible to overcome. To succeed, you must compensate for the lost points by answering significantly more questions correctly on the exam compared to the previous year.
How Many Extra Correct Answers Do You Need?
Understanding how many extra net questions you need to answer to make up for a 27-point loss helps you set realistic goals. (Note: The exact point value of a question changes slightly every year based on national averages and standard deviation, so these figures are estimates.)
- Compensating in the TYT (Basic Exam): One correct answer in the TYT brings roughly 1.3 to 1.4 points. To cover a 27-point loss, you would need to score approximately 19 to 21 more correct net answers in the TYT than you normally would.
- Compensating in the AYT (Field Exam): Questions in the AYT carry more weight. For instance, in Mathematics or Science, a correct answer yields about 3 points. To cover the 27-point gap, you must secure an extra 9 to 10 correct net answers in the AYT.
The Strategic Takeaway:
If you honestly believe that you can boost your knowledge enough to score 20 more net answers in TYT and 10 more in AYT compared to last year, then retaking the exam despite the penalty might be worth it. However, if you feel you are already performing near your absolute maximum potential, that 27-point deduction might keep your dreams out of reach for another year. In such cases, the most rational strategy is often to wait one full year (without taking the exam or making preferences) until the penalty expires, and then compete with your full, unbroken OBP.
Planning Your Strategy
The Broken OBP is a heavy price paid for the "let's just apply anywhere" mindset during the university preference period. Therefore, you must ask yourself a vital question for every single department you list on your preference form: "If I am placed here, will I happily study there for four years?" If the answer is "No," you should immediately remove that choice from your list.
