Short writeup:
2025 TMJC H2 Chemistry JC1 WA1: The Most Exhausting Paper Yet?
The 2025 TMJC H2 Chemistry JC1 WA1 is, without doubt, one of the most demanding WA1 papers I’ve reviewed this year—and not for the reasons you might expect. While many students brace themselves for tough conceptual twists or obscure application-based questions, this paper takes a different route. It skips Section A entirely—there are no MCQs—and jumps straight into full-length structured questions totaling 30 marks. From the start, it's clear this paper is designed to wear students down through sheer volume and technicality.
What sets this paper apart is how it leaves no part of the syllabus untouched. Within the three core topics tested—Mole & Redox, Stoichiometry, and Atomic Structure—every concept gets its turn. The Mole & Redox segment, for example, doesn’t stop at the usual practical-style setup. It continues into empirical formula, limiting reagents, and even questions that challenge students to link multiple concepts together. While this level of depth might feel familiar to students who studied O-Level Pure Chemistry, it’s likely to catch those from a Combined Science background off guard.
But the real difficulty of this paper isn’t rooted in conceptual obscurity. It’s the sheer workload. Every question is calculation-heavy, multi-step, and mentally draining. Students reported struggling to finish the paper in time, and even those who managed to complete it found themselves making uncharacteristic errors. It’s a paper that tests stamina just as much as understanding. Those who performed well deserve real recognition—not just for their content knowledge but also for their time management and mental endurance.
In short, while this paper isn’t groundbreaking in terms of creativity, it’s a solidly designed, technically intensive set that covers the foundational chapters thoroughly. It may not introduce new insights, but it’s incredibly useful for students looking to refine their chemical calculation skills and test their ability to stay composed under pressure.
