H3 Economics is an extension of H2 Economics, which is a core subject in the Junior College (JC) curriculum in Singapore. H3 Economics covers topics beyond the H2 Economics curriculum and provides students with a more in-depth understanding of advanced economic concepts and theories.

H2 Economics covers a broad range of topics, including microeconomics, macroeconomics, international economics, and monetary economics. It provides a good foundation in economic concepts and theories, and prepares students for university-level courses in economics or related fields.

H3 Economics, on the other hand, covers topics beyond the scope of H2 Economics, such as advanced microeconomic theory, game theory, econometrics, and advanced macroeconomic theory. It requires a higher level of analytical and mathematical proficiency, and is recommended for students who are passionate about economics and intend to pursue further studies or careers in research, academia, or related fields.

The main difference between H2 Economics and H3 Economics is the level of depth and complexity. H3 Economics is more challenging and requires a higher level of proficiency in economics, mathematics, and critical thinking skills than H2 Economics. It is a specialized course for students who have a strong interest in economics and are seeking an extra challenge beyond the standard H2 Economics curriculum.

In terms of university admissions, H3 Economics is not a requirement for most undergraduate courses. However, it is a valuable asset for students who are planning to pursue further studies or careers in research, academia, or related fields. It can also be beneficial for students who wish to differentiate themselves in their university applications by demonstrating their passion and proficiency in economics.

Overall, H2 Economics provides a strong foundation in economic concepts and theories, while H3 Economics provides an opportunity for students to deepen their understanding of advanced economic concepts and theories. Students should consider their interests and career aspirations when deciding whether to take H3 Economics.
