General Ability vs. General Knowledge in EKPSS: Which Test Carries More Weight?

When preparing for the Disabled Public Personnel Selection Examination (EKPSS), almost every candidate faces a strategic dilemma: "Should I focus my studying on General Ability (Turkish and Math) or General Knowledge (History, Geography, and Citizenship)?"

Many students ask questions like, "I am terrible at Math, can I just memorize History and still get a high score?" or "Does a correct answer in Math give me more points than a correct answer in Geography?"

To answer these questions, we must look at how ÖSYM (the testing authority) applies mathematical weighting and standard deviation to the exam results. In this article, we will analyze which test historically carries more weight and how you should structure your study plan accordingly.

You can simulate exactly how the weighting affects your specific scenario by testing different coefficients in our EKPSS Score Calculator.

The Basic Weighting Rule (The 50/50 Myth)

According to the official exam guidelines, the EKPSS consists of 60 questions: 30 for General Ability (GA) and 30 for General Knowledge (GK). On paper, before the exam is administered, both tests are assigned an equal weight of 50%.

The basic formula looks like this:
Final Score = Base Score + (GA Net * GA Coefficient) + (GK Net * GK Coefficient)

If the tests remained strictly 50/50, the GA Coefficient and the GK Coefficient would be exactly the same. However, this is almost never the case once the exam is actually graded.

How Test Averages Shift the Weight (Standard Deviation)

Once all candidate exams are graded, ÖSYM calculates the national average and standard deviation for both the GA and GK sections. This is where the "weight" of the tests shifts. If a test is statistically harder (meaning the national average is low), the coefficient for that test increases, making every correct answer worth more points.

When we look at the statistical trends of the EKPSS over the past decade, a clear pattern emerges:

The General Ability Advantage: The General Ability section contains Mathematics. Historically, a vast majority of EKPSS candidates struggle significantly with the Math portion. Because so many candidates leave the Math questions blank or answer them incorrectly, the overall national average for the General Ability test is usually quite low. As a result, the standard deviation pushes the GA Coefficient higher.
The General Knowledge Saturation: The General Knowledge section (History, Geography, Citizenship) relies heavily on reading comprehension and memorization. Candidates tend to study heavily for these subjects, and consequently, the national average for the GK test is usually higher. Because candidates perform better on average, the standard deviation lowers the GK Coefficient slightly.

The Verdict: While it is not an absolute rule, historical data strongly suggests that General Ability nets (due primarily to the difficulty of Mathematics) generally carry a higher point coefficient than General Knowledge nets.

Coefficient Simulation: A Tale of Two Candidates

To illustrate how this slight shift in test weight impacts the final score, let's run a simulation using the logic built into the EKPSS Score Calculator.

Let's assume the following post-exam coefficients based on national averages:

GA Coefficient: 0.8 (Because Math was very difficult)
GK Coefficient: 0.6 (Because History was relatively easy)
Base Score: 40

Candidate A (The Math Whiz):
Candidate A is excellent at General Ability but terrible at memorizing History.

GA Net: 30
GK Net: 0
Calculation: 40 + (30 * 0.8) + (0 * 0.6) = 64 Points

Candidate B (The History Buff):
Candidate B ignores Math completely and achieves a perfect score in General Knowledge.

GA Net: 0
GK Net: 30
Calculation: 40 + (0 * 0.8) + (30 * 0.6) = 58 Points

Even though both candidates answered exactly 30 questions correctly, Candidate A scored 6 points higher simply because they excelled in the statistically harder test.

However, taking the approach of Candidate A or Candidate B is actually a terrible study strategy. Here is why.

The Golden Rule: The Power of Balanced Scoring

The most critical factor in standard deviation algorithms is that scoring above average in both metrics creates a compounding positive effect on your score. Relying on just one test, even the one with the higher coefficient, severely caps your maximum potential score.

Let's look at a third candidate:

Candidate C (The Balanced Strategist):
Candidate C splits their effort evenly.

GA Net: 15
GK Net: 15
Total Nets: 30
Calculation: 40 + (15 * 0.8) + (15 * 0.6) = 40 + 12 + 9 = 61 Points

In our simplified calculator, Candidate C scores right in the middle. However, in ÖSYM's true algorithm, Candidate C often receives a bonus positive deviation push for being above average in multiple distinct testing domains, often pushing their score closer to or above Candidate A's in real-world results.

Strategic Takeaways for Your Study Plan

So, how should you structure your preparation given this information?

Maximize Your Strengths, Don't Ignore Weaknesses: If you are excellent at General Knowledge, secure those points, but do not abandon General Ability. Even solving 3 to 5 easy math questions or focusing heavily on the Turkish grammar section can provide a massive boost to your GA net.
Do Not Fear Math: Every question in the GA test has the same weight. If you cannot do algebra, focus on basic arithmetic or logic puzzles. Securing just a few math nets puts you ahead of thousands of candidates who leave the section entirely blank.
Run Your Own Scenarios: As you take practice exams, input your net scores into the EKPSS Score Calculator. Try adjusting the GA Coefficient higher than the GK Coefficient to simulate a math-heavy difficulty, and see exactly how many points you stand to gain or lose based on your current study trajectory.

Ultimately, while General Ability often provides a slight coefficient edge, the most successful EKPSS candidates are those who build a balanced, resilient study strategy across both disciplines.
