what is the source of this 4u math paper (1 Viewer)

[ZHANDONG]

it looks reasonably hard, like BOS trials, would u agree? Is this a crowd-sourced 4u paper or what is the source?

what is the difficulty level of this paper?

An Extension 2 math paper typically involves more advanced mathematical concepts and problem-solving skills than what might be assessed in a standard IQ test. However, there can be some overlap between the types of reasoning skills assessed in an IQ test and the skills required for a math extension paper.

1. Reasoning with Numbers: In an Extension 2 math paper, questions involving complex number theory, advanced calculus, or abstract algebra may require reasoning with numbers. This could involve understanding patterns, relationships, and properties within numerical systems, which also taps into numerical reasoning assessed in IQ tests.
2. Reasoning with Logic: Logic is fundamental in mathematics, especially in proofs and problem-solving. Extension 2 math papers often include questions that require logical reasoning to formulate proofs, make deductions, or analyse mathematical structures. Similarly, IQ tests assess logical reasoning through puzzles, sequences, and deductive reasoning tasks.
3. Reasoning with Words: While not as directly applicable to a math paper, reasoning with words involves understanding and interpreting instructions, problem statements, and mathematical language. This skill can be important for interpreting math problems accurately and effectively, both in IQ tests and in math extension papers.
4. Reasoning with Space: Spatial reasoning involves visualizing and manipulating objects in space, which is crucial in geometry, trigonometry, and advanced calculus. Extension 2 math papers may include questions that require geometric proofs, visualizing higher-dimensional spaces, or manipulating geometric objects. Spatial reasoning is also sometimes assessed in IQ tests through tasks such as pattern completion, shape analogies, and mental rotation.

While the specific content and focus may differ between an IQ test and an Extension 2 math paper, the underlying reasoning skills are interconnected. Both assessments require the ability to analyse information, identify patterns, make logical deductions, and apply problem-solving strategies, albeit in different contexts. Therefore, proficiency in the types of reasoning assessed in an IQ test can contribute to success in solving complex mathematical problems presented in Extension 2 math papers.

Hope this helps @ZHANDONG !

The cover is a modified version of that used by the Independent Schools papers, as is the table on page 2 for MCQ papers... but it's not the 2020 Independent paper. The way things like square roots appear makes it look like it's not from a professional source. The repeating of the diagram in Q6 and 12(d) and the exclusion of using a known and established result in Q12(d)(ii) adds to that impression. Q14(b) is a standard result from the old syllabus, but impossible as the diagram is incomplete (there should be a tangent to the curve at x₂ that crosses the x-axis at x₁). But, there are some good questions that may have been lifted from a variety of sources.

isn't it much harder than the independent papers?
