Our tutorial lessons shall focus on teaching students to use scientific vocabulary when writing analysis, evaluation, and examination answers. Students will also develop scientific thinking skills, which they may apply when designing experiments that implement the most efficient investigative strategies. Major topics in the study of IGCSE Biology include: cell functions and control; genetics; natural selection; genetic modification; health disease development of medicines; plant structures functions; animal coordination control homeostasis; exchange and transport; and ecosystems material cycles. Topics for GCE AS (IAS), A-Level (IA2), International Advanced Level (IAL), SAT Subject Test, AP, and IB Diploma include: structure and function of carbohydrates, lipids, and proteins; enzymes; passive and active transport; DNA, RNA, and PCR (polymerase chain reaction); protein synthesis; mutation; dihybrid crosses; ethics; ultrastructure of eukaryote and prokaryote cells; meiosis; genotypes; stem cells; biodiversity and adaptations; taxonomy; global warming; evolution and speciation; structure of bacteria and viruses; immunology; ATP; glycolysis; anaerobic respiration; ventilation and cardiac output; the brain and the nervous system; hormonal coordination; and the Human Genome Project. At Key Stage 3 (KS3), student will learn cellular, skeletal and muscular systems of living organisms; nutrition, digestion, and excretion; respiration and photosynthesis; health and disease; reproduction in plants and humans; ecosystems, habitats, food chains and food webs; genetics, inheritance, selective breeding, variation, evolution, extinction, and biodiversity; human impact on the environment; nerves and hormones; and transport.

Biology Tutor, 2020 – present

Mr Giles Chambers graduated from the University of Oxford with a Master of Engineering (Hons) in Materials Science. Before joining IST as a Bio Tutor, Mr Chambers tutored in Portugal and Great Britain. Gil’s interest in biology might not be obvious from his physical science degree, but indeed it is a fundamental consideration of both his own research style and his passions. In the 4th year of his degree, Gil utilised freeze-casting, a processing technique inspired by nature, to craft intricate hierarchical structures with nanomaterials. He encourages students not to see the division between sciences, and by targeting the weaknesses of each individual student, he encourages students to love learning by focusing on their interests. On his Biology GCSE and A-levels, Gil earned A/A*s. Mr Chambers tutors Biology to IGCSE level.

Senior Biology Tutor, 2009 – present

Mr Daniel Chan holds a Bachelor of Science Degree (Hons.) in Chemistry from the University of New South Wales, Australia, and a Bachelor of Science Degree (Advanced) from the University of Sydney, Australia, majoring in Chemistry and Biochemistry. Daniel is now in the final stages of Doctorate in Chemistry at the University of Cambridge.

Since 2009, Daniel has been tutoring at International Scholars Tuition School. He has tutored students from German Swiss International School on the SAT Biology Subject Test. He has also taught respiration and photosynthesis to an OCR A-Level Biology student from Harrow School, and transport and microorganisms to a AQA GCSE Biology student from The Royal High School, UK. Two of Daniel’s Biology students last year from GSIS were admitted early on the fast track basis to study medicine at the University of Hong Kong (HKU). Daniel has also tutored Cardiff Sixth Form College and King’s Scholars at Eton College.

Principal Biology Tutor, 2005 – present

Mr Don Ho has been tutoring Biology 11+ and 13+ Common Entrance and IGCSE to Hong Kong students at 1ST since 2005. Many of Don’s 13+ Science students have gone on to study at Winchester College, Eton College, Oundle School, Cheltenham Ladies College, Wycombe Abbey, and Malvern St James. Furthermore, many of Don’s students have scored A* on their IGCSEs.
