Syllabus / Assessment

Biology H2 Exam Code: 9744 


Candidates taking H2 Biology are assumed to have knowledge and understanding of Biology at 'O' level, as a single subject or as part of a balanced science course.

The syllabus has been arranged in the form of Core and Extension content to be studied by all candidates.

The syllabus places emphasis on the applications of biology and the impact of recent developments on the needs of contemporary society.

Experimental work is an important component and should underpin the teaching and learning of biology.

The value of learning H2 Biology ultimately hinges on the development of a scientific mind and dispositions while addressing the broader questions of what life is and how life is sustained. The Science Curriculum Framework developed by the Ministry of Education elaborates on the development of the scientific mind and dispositions. Through the study of the H2 Biology course, students will be prepared for life science-related courses at university and, consequently, careers that are related to this field.

Paper 1 (1 h, 30 marks)

This paper will consist of 30 compulsory multiple choice questions. All questions will be of the direct choice type with 4 options.

Paper 2 (2 h, 100 marks)

This paper will consist of a variable number of structured questions, all compulsory, including data-based or comprehension-type questions. These include questions which require candidates to integrate knowledge and understanding from different areas of the syllabus.

Paper 3 (2 h , 75 marks)

This paper will consist of a variable number of long structured questions, all compulsory, including databased or comprehension-type questions and one free-response question of 25 marks. These include questions that assess the higher-order skills of analysing, making conclusions and evaluating information and require candidates to integrate knowledge and understanding from different areas of the syllabus.

Section A (50 marks) will comprise two or more compulsory long structured questions. There will be one or more stimulus materials which may be taken or adapted from a source such as a scientific journal or book which may not necessarily relate directly to the content of the syllabus. Questions may require candidates to explain terms used in the passage, analyse data, justify decisions, perform calculations and draw conclusions based on information in the stimulus material.

Section B (25 marks) will comprise two free-response questions, from which candidates will choose one. The quality of scientific argumentation and written communication will be given a percentage of the marks available.

Paper 4 (40 marks)

This paper will assess the following skills areas:
  • Planning (P) 
  • Manipulation, measurement and observation (MMO) 
  • Presentation of data and observations (PDO) 
  • Analysis, conclusions and evaluation (ACE) 

The assessment of Planning (P) will have a weighting of 5%. The assessment of skill areas MMO, PDO and ACE will have a weighting of 15%.

The scope of the practical paper is indicated in the Practical Assessment section. The assessment of PDO and ACE may also include questions on data-analysis which do not require practical equipment and apparatus. Candidates will not be permitted to refer to books and laboratory notebooks during the assessment.
