2025 YIJC H2 Chemistry Paper 3 Review: A Clean Benchmark for What Paper 3 Really Looks Like
The 2025 YIJC H2 Chemistry Paper 3 is a solid demonstration of what a typical A Level H2 Chemistry Paper 3 looks like when stripped of unnecessary gimmicks. It presents a fair difficulty, a clean structure, and a reasonable combination of topics that students are expected to be comfortable with at this stage of their preparation.
One of the strongest aspects of this paper lies in its relevance. For Paper 3, students usually anticipate questions that test unfamiliar organic mechanisms, require pattern recognition, or demand that they extrapolate beyond memorised reactions. This paper aligns well with that expectation. The questions are recognisable in structure, yet still require students to genuinely understand what they are doing rather than blindly apply rehearsed steps.
That said, the insights offered by this paper are sufficient, but not spectacular. Many of the questions could have been stretched further with better storytelling or real-life context. The concepts tested are sound and meaningful—these are exactly the types of ideas I enjoy unpacking with my own students in class—but the lack of contextual framing causes the paper to feel a little flat. It tests understanding well, but it doesn’t provoke curiosity.
As a result, this is not a difficult paper. In many ways, it represents the baseline standard that students should expect from an A Level H2 Chemistry Paper 3. The questions are generally low in context and high in emphasis on raw concepts and technical execution. At the same time, it is not a tedious paper either. A large proportion of the paper focuses on organic chemistry, which tends to be more time-efficient for students who are well-trained in recognising reaction patterns.
Overall, this is a good paper—one that could have been better, but still serves a clear purpose. It takes inspiration from multiple schools’ prelim papers, and some students may even see it as a compilation of “all-star” prelim-style questions. I would recommend this paper to students looking for a reliable timed practice, especially those who want exposure to commonly tested Paper 3 question types without being overwhelmed.
