In secondary school, not all grades count equally toward your final grade. This is determined by weighting factors. Understanding how weights work can help you study smarter and improve your average.
What are weighting factors?
Weighting factors (or weights) determine how heavily a grade counts when calculating your average. A grade with weight 3 counts three times as much as a grade with weight 1.
This system is used because not all test types require the same level of knowledge and preparation. A test covering an entire chapter logically weighs more than a small quiz.
Typical weights in secondary school
Although weights vary per school and subject, these are common examples:
- Exam/Major test: weight 3-5
- Written quiz (SO): weight 1-2
- Homework assignment: weight 1
- Oral exam: weight 1-2
- Practical assignment (e.g., lab work): weight 2-3
Always check your school's PTA (Program of Testing and Completion) for exact weights!
Calculation example: Impact of weights
Suppose you have the following grades for Dutch:
- Exam: 5.0 (weight 3)
- Quiz: 8.0 (weight 1)
- Homework: 9.0 (weight 1)
Weighted average: (5.0×3 + 8.0×1 + 9.0×1) / (3+1+1) = (15+8+9) / 5 = 32/5 = 6.4
Without weights the average would be (5+8+9)/3 = 7.3. Due to the weight, the low exam grade counts more heavily and the average is lower.
The impact of weights on your average
Why it's important to understand weights:
- A low grade on a heavily weighted test is harder to compensate
- Many small successes (quizzes, homework) can't always make up for a bad exam
- Strategically focusing on heavy tests can efficiently raise your average
Where do I find the weights?
You can find the weights for your subjects via:
- The PTA (Program of Testing and Completion) - available through school or Magister
- Magister or SOMtoday - your grade overview often shows the weight
- Ask your teacher - they can explain the weights for their subject
Strategic tips
- Focus extra on tests with high weights - this is where most gains can be made
- Don't neglect quizzes or homework - even small weights add up
- If you fail an exam, immediately ask about retake opportunities
- Calculate in advance what grade you need to achieve your desired average
