What’s Difference Between H1 And H2 Chemistry


Should I study in JC chemistry, and should I choose H1, H2, or H3 Chemistry?”

“How do H1 and H2 chemistry compare to the ‘O’ Level chemistry I’m learning?”

“Will taking H2 or H3 Chemistry boost my chances of getting into college?”

These are some of the most popular inquiries from prospective high school students. Intuitively, we understand that Junior College (JC) Chemistry can cover more advanced topics than high school chemistry.

But there’s a lot more that students don’t understand. The differences between H1 and H2 chemistry are discussed in this article. This is achieved not only from the syllabus or evaluation standpoint but also in terms of potential prospects.

An Overview of H1 and H2 Chemistry

For instance, you can expect a wider variety of topics and a deeper analysis of H1 and H2 Chemistry material than in ‘O’ Level Chemistry. Furthermore, the emphasis of the syllabus moves from factual content to scientific principles implementation. As a result, experimental work becomes an important part of the material.

Students must show the following skills to perform well at either the H1 or H2 levels:

  • An interpretation of scientific knowledge’s existence
  • Capacity to use scientific investigation skills

Comparing the H1 and H2 Chemistry Syllabuses

In comparison to its H2 equivalent, H1 Chemistry covers considerably less material. This refers to the breadth of topics as well as the complexity of each one. The following are some examples of syllabus differences:

Solubility Equilibria, Electrochemistry, and Transition Elements are all topics covered in H2 Chemistry. H1 Chemistry, on the other hand, ignores them completely.

Chemical Energetics, Reaction Kinetics, and Chemical Equilibria are covered in both H1 and H2 Chemistry. The depth of content in H1 for these subjects, on the other hand, is notably less.

It should also be remembered that H1 students do not have to do any lab work and therefore do not have to take the SPA test. H2 students, on the other hand, have regular practice sessions during the school year.

Comparing the H1 and H2 Assessment Formats

As previously mentioned, H2 Chemistry requires a realistic test, while H1 Chemistry does not. Furthermore, the number of papers, as well as the weighting of query types, vary.

Comparing H1 and H2 Assessment Objectives

Aside from the different assessment formats, the goals of H1 and H2 Chemistry are also different. The variations in evaluation objectives reflect this.

How about the chemistry of H3?

H3 Chemistry is only open to students who excelled in their first year of high school. The subject aims to help the top 10-15% of students in the cohort advance their education. As a result, it is not a topic that is followed when entering JC.

H3 Chemistry, unlike H1 or H2, does not have a prescribed syllabus. Instead, students can choose from a variety of different programs. This may be in the form of university undergrad modules or in-depth analysis. We encourage you to contact us or seek advice from your respective JCs for more information on H3 Chemistry.

Changing from Combined Science to Junior Chemistry

If you’re studying chemistry for your ‘O’ Levels, you’ll understand the distinctions between mixed science and pure chemistry. If you’ve only ever taken chemistry as part of combined science, the issue of whether you should study H2 Chemistry or even H1 Chemistry arises.

Pure chemistry students, on the other hand, have a small advantage because they have covered the fundamentals of the following topics:

  • Electrolysis is a process that involves the use of
  • Bonding with metals
  • Kinetics and Structures of Covalent Compounds Concepts

On the other hand, all other subjects are largely fresh, so everyone starts on an equal footing. As a result, we conclude that your success will be determined by your consistency, effort, comprehension, and enthusiasm for Chemistry.
