Short writeup:
The 2022 Anglo-Chinese Junior College (ACJC) H2 Chemistry paper is an interesting and niche exam that stands out due to its heavy focus on physical chemistry. Unlike most JC1 papers, which test common topics like organic chemistry and reaction kinetics, this paper delves into areas like acid-base equilibrium and solubility product—topics typically taught in JC2 at many other schools. This makes the paper particularly valuable for students seeking a more specialized practice experience.
This ACJC paper is centered around calculation-intensive physical chemistry, offering students a chance to sharpen their problem-solving skills in a unique way. While most promo papers share a core set of topics, the focus on acid-base equilibrium and solubility product means that certain sections may not be as directly useful to students outside of ACJC, especially if their school hasn’t covered these topics yet.
One of the key strengths of this paper lies in its insightful, contextual anchor questions related to physical chemistry. While these questions add value, the paper does feel imbalanced, as it doesn’t offer enough focus on other important areas like inorganic chemistry. This may limit its appeal for students looking for a well-rounded practice session.
Because the paper is so calculation-heavy, many students may struggle with time management. The format is demanding, requiring both Paper 1 and Paper 2 to be completed in a two-hour window. While the individual questions are not excessively difficult, their time-consuming nature, particularly the calculations, presents a challenge that’s different from what students might face in other promo exams.
The 2022 ACJC H2 Chemistry promo paper is best suited for students who have already been introduced to topics like ionic equilibrium and solubility product. For these students, it’s an excellent timed practice to help improve time management and deepen their understanding of complex, multi-step calculations. For others, the physical chemistry questions, such as those on energetics, can still offer great value as practice even if the entire paper isn't directly applicable to their syllabus.
