Whether you aced the exam or found it challenging, knowing how the marking scheme operates can shed light on the specific areas where you excelled or where you might need to focus your efforts. This guide breaks down the key features of the 2021 OL Maths paper marking scheme, providing clarity and a deeper understanding of the exam’s evaluation process.
Paper Breakdown and Weighting
The 2021 Ordinary Level Maths paper was divided into two distinct parts, each with its own unique structure and marking criteria:
Paper 1 (Short Answer Questions)
This section comprised a series of short answer questions, designed to assess your understanding of fundamental mathematical concepts and your ability to apply them in straightforward scenarios. The questions were generally structured as follows:
- Part A: This encompassed basic computations and calculations requiring straightforward application of key mathematical principles. These questions were typically assigned a relatively low mark value, focusing on the ability to execute fundamental mathematical operations accurately.
- Part B: This section involved more complex calculations and applications of mathematical concepts. Here, you were expected to demonstrate a deeper understanding of the subject matter and a greater ability to interpret and solve problems. The questions in Part B often carried a higher mark value, reflecting their increased difficulty and focus on higher-order thinking skills.
Paper 2 (Structured Questions)
Paper 2 presented a series of structured questions, testing your ability to tackle more complex mathematical problems requiring a deeper understanding of concepts and principles. These questions were designed to assess your capacity to apply mathematical knowledge in different contexts and provide clear and well-articulated solutions. A typical structure for Paper 2 questions is as follows:
- Part A: This section usually involved a series of short, focused questions within each larger question. These questions often built upon each other, requiring you to use the result of one calculation in subsequent steps. They assess your ability to apply mathematical concepts in a step-by-step fashion.
- Part B: This section often presented longer, more involved questions requiring you to demonstrate a comprehensive understanding of the topic. These questions typically involved multiple steps and might require you to combine different mathematical concepts to arrive at a solution. The mark value for these questions was often higher, reflecting their increased complexity and emphasis on analytical reasoning and problem-solving skills.

Understanding the Weighting System
Each paper was assigned a specific weight, reflecting its relative importance in the overall assessment of your mathematical abilities. Paper 1 carried a specific percentage of the total exam score, while Paper 2 held the remaining percentage, ensuring a balanced assessment of your abilities in both short-answer and structured question formats. Your score on each paper was then factored into the overall exam result, providing a comprehensive evaluation of your mathematical understanding.
Marking Criteria: Delving Deeper
Beyond the structure of the papers, the core of the marking scheme lies in the detailed criteria used to evaluate each question. This section provides a glimpse into the specific elements considered during the marking process:
Correctness & Accuracy: The Foundation
The fundamental basis of the marking scheme hinges on the correctness and accuracy of your answers. Did you perform the calculations accurately? Did you follow the correct steps and procedures? A significant portion of the marks is awarded for getting the answers right. The marking scheme outlines the precise values that are considered correct, ensuring consistency and fairness in the evaluation.
Methodical Approach: Demonstrating Your Understanding
Beyond simply getting the final answer right, the marking scheme also emphasizes demonstrating your understanding of the underlying mathematical concepts. Did you use the appropriate methods and formulas? Did you show your working clearly and logically? Demonstrating your step-by-step reasoning earns valuable marks, showcasing your comprehension of the principles at play.
Communication & Clarity: Expressing Your Solutions
Communication is key in mathematics, and the marking scheme reflects this. Are your answers presented neatly and clearly? Did you use correct mathematical notation and language? Effective communication ensures that your working is readily understandable and contributes to a higher mark. Clear and concise explanations can earn you extra points and impress the examiners.
Problem-Solving Skills: Applying Knowledge to Context
A core focus of the marking scheme is on assessing your problem-solving skills. Did you successfully interpret and analyze the given information? Did you apply the appropriate mathematical concepts to reach a solution? Demonstrating your ability to tackle problems effectively is crucial for securing a strong score.
Examining the Specifics: Examples from the 2021 Paper
To provide a more concrete understanding of the marking scheme in action, let’s look at a few examples from the 2021 OL Maths paper:
Example 1: Algebra
Consider a question that requires you to solve a quadratic equation. The marking scheme would outline the following criteria:
- Correct application of the quadratic formula: Correctly substituting the coefficients of the quadratic equation into the formula. This step earns marks for demonstrating understanding of the appropriate method.
- Accurate calculation: Performing the calculations within the formula without errors. This step ensures the correctness of your solution.
- Final answer: Providing the correct solutions to the quadratic equation. This step earns you the final marks for obtaining the correct result.
Example 2: Geometry
Imagine a question asking you to calculate the area of a triangle given its sides. The marking scheme would likely specify the following:
- Correct identification of Heron’s Formula: Recognizing that this formula is appropriate for calculating the area of a triangle given its sides. This demonstrates your understanding of relevant formulas.
- Accurate application of Heron’s Formula: Correctly calculating the semi-perimeter and using it in the formula. This step ensures the accuracy of your calculations.
- Final answer: Obtaining the correct area of the triangle. This step marks the successful application of the formula and secures the final score.
Example 3: Statistics
Suppose you encountered a question on calculating the mean of a data set. The marking scheme would likely outline the following criteria:
- Correct formula for calculating the mean: Understanding and applying the formula for the mean of a data set. This step demonstrates your understanding of statistical concepts.
- Accurate summation of the data values: Correctly adding up all the values in the data set. This step ensures the accuracy of your calculation.
- Correct division by the number of data points: Dividing the sum of data values by the total number of data points. This step ensures the correct application of the mean formula.
- Final answer: Obtaining the correct mean value for the data set. This step marks the successful execution of the statistical calculation.
Navigating the Marking Scheme: Tips for Success
While the marking scheme might appear complex at first glance, understanding its core principles can equip you with valuable strategies to excel in future exams:
Focus on the Fundamentals
The marking scheme emphasizes mastery of fundamental mathematical concepts. Ensure you have a strong foundation in key topics like algebra, geometry, trigonometry, and statistics. Practice regularly to build confidence and fluency in these areas.
Demonstrate Your Working
Don’t just provide the final answers. Show your working clearly and logically, explaining each step. This demonstrates your understanding of the processes involved and earns valuable marks.
