Our expert IB math tutors at Elite Prep cover the key areas of focus for the 2024 math exam

Number and Algebra:

Standard Form, Accuracy, and Estimation: Pay attention to details in these manageable topics.

Sequences and Finances: Focus on trickier questions like using the compound interest formula with different periods. Understand the finance application thoroughly, and use table functions for modeling sequences and investments.

Sets of Numbers: Memorize symbols for different sets. It’s crucial for understanding various mathematical concepts.

Geometric Sequences:

Example 1: Finding common ratios in sequences. For instance, calculating population growth in a town as a geometric sequence.

Example 2: Recognizing geometric sequences in real-world scenarios, like yearly population increases or decreases in value.

Example 3: Paying attention to specifics, like calculating the total distance a ball travels considering each bounce as a geometric sequence.

Mathematical Models:

Remembering the axis of symmetry formula is key, as little is provided in the formula booklet. Understanding general expressions for linear, quadratic, and exponential models is also essential.

Graph Drawing and Calculus Skills:

Example 1: Importance of accuracy in graph drawing for securing marks. Attention to scales, labels, and smooth curves is crucial.

Example 2: Solving quadratic equations by working backwards from given information, like the axis of symmetry or specific points on the graph.

Geometry and Trigonometry:

Example 1: Understanding angles and slopes in 3D shapes, like distinguishing between the height of a pyramid and its triangular faces.

Example 2: Choosing the most efficient trigonometric rule for a given situation, such as using SOHCAHTOA instead of the cosine rule in right-angled triangles.

Logic, Sets, and Probability:

Remembering implications and focusing on truth combinations.

Example 1: Being systematic with truth tables.

Example 2: Correctly interpreting shaded areas in Venn diagrams.

Example 3: Understanding conditional probabilities in tree diagrams.

Statistics:

Proficiency with a graphing calculator is necessary for tasks like handling one-variable and two-variable data, linear regression, and chi-squared tests.

Example 1: Handling inverse normal calculations with two boundaries, such as finding a specific value within a normal distribution.

Calculus:

Example 1: Tackling optimization problems in calculus, especially those involving 3D shapes. This includes understanding volume and surface area relationships and finding optimal values.

Each of these points and examples provides a comprehensive guide for students aiming for high grades in Maths Studies exams, emphasizing the importance of understanding concepts, practical application, and strategic problem-solving.
