H2 Chemistry vs H3 Chemistry 

For Singapore JC’s, the H2 chemistry syllabus covers a range of topics that builds on knowledge, understanding and skills. Students that are able to score well in the H2 syllabus will be able to take H3 chemistry,  which provides greater depth and rigour in the subject for students pursuing further studies in chemistry related fields.
