Mr Angus Chia has spent 10 years helping students strengthen their Chemistry knowledge and achieve better results through private tuition, small group classes and student care programmes. A former student of St. Joseph’s Institution and National Junior College, and an NTU alumnus, he earned 9 distinctions at the GCE O-Level examinations. He specialises in building strong Chemistry fundamentals, explaining complex concepts, mastering chemical equations and calculations, and developing effective exam techniques for O-Level Chemistry success.

Chemistry Tuition Options in Singapore
Chemistry rewards students who understand why reactions happen, not just how to balance an equation. At TutorSay, we provide personalised O Level Chemistry tuition in Singapore for Secondary 3 and Secondary 4 students through one-to-one lessons, small-group classes, and home tuition. Every option follows the MOE syllabus and is built around each student's learning needs, school topics, and GCE O Level goals.
Receive individual attention with lessons tailored to the student's pace, school topics, and target O Level grade, from catching up on Sec 3 concepts to final Sec 4 revision.
Learn through structured explanations, collaborative problem-solving, and guided practice with school prelim papers and O Level past year papers.
Learn at home with a private Chemistry tutor who guides students through concepts, equations, and mole calculations, without the travel time after a long school day.
Strengthen chemical concepts, equations, mole calculations, and exam techniques for the multiple-choice, structured, and practical papers.
About Our Chemistry Tuition
TutorSay provides structured Chemistry tuition for Secondary 3 and Secondary 4 students in Singapore preparing for the GCE O Level. Lessons follow the MOE syllabus and focus on understanding scientific concepts, applying chemical principles, and writing the precise answers that SEAB examiners look for. Students practise school-style and O Level past year paper questions, with targeted help on the topics where marks are being lost.
Chemistry Programme
The programme moves from core ideas such as atomic structure and bonding to O Level exam practice, so students understand the Singapore secondary Chemistry syllabus and know how to answer Chemistry questions accurately.
Learn atomic structure, chemical bonding, chemical equations, the mole concept and stoichiometry, acids, bases and salts, redox reactions, rate of reaction, the Periodic Table, metals, and organic chemistry, matched to what the student's school is teaching.
Develop accuracy in mole calculations, scientific explanations, and structured questions, with time management practice using O Level past year papers, ten-year series (TYS) questions, and school prelim-style papers.
Why TutorSay for Chemistry
TutorSay helps Singapore secondary students make sense of Chemistry through clear explanations, regular practice with equations and calculations, and guidance that suits each student's needs and school.
Lessons focus on the topics a student finds hardest, whether that is mole calculations, bonding, or organic chemistry.
Students work through Chemistry questions together, discussing methods and learning from each other's reasoning.
Abstract ideas such as bonding, redox, and stoichiometry are explained step by step with clear examples that connect to what students see in school.
Topic-by-topic revision and O Level exam-style questions build accuracy in equations, calculations, and written explanations before mid-year exams, prelims, and the GCE O Level.
Lessons follow the MOE syllabus for both O Level Chemistry and the Chemistry component of Combined Science (Chemistry/Physics).
Regular check-ins on equations, calculations, and written answers keep lessons aimed at the Chemistry topics that need the most work, so students stay on track for the grade they need for JC or polytechnic admission.
Combined Science Chemistry
Combined Science students need a solid grasp of the Chemistry component, from chemical equations to calculations. Our O Level Combined Science Chemistry tuition in Singapore helps Sec 3 and Sec 4 students master key concepts and prepare effectively for school exams and the GCE O Level.
Key Chemistry topics in the Combined Science syllabus are explained step by step so students understand the reasoning behind each answer.
Students practise chemical equations and mole calculations to improve accuracy and reduce careless mistakes.
Structured questions, school prelim papers, and past year paper practice help students apply Chemistry concepts and write the answers examiners expect.
Each student gets lessons built around the Chemistry topics they find hardest, at a pace that suits them and fits around school and CCA commitments.
Chemistry Practical Preparation
Practical skills are an important part of O Level Chemistry in Singapore. Through guided practice with practical past papers and school lab-style questions, students learn to follow experimental procedures, record observations accurately, and explain results with confidence.
Practise with O Level practical past paper style questions so the format, apparatus, and SEAB marking expectations feel familiar before the exam.
Strengthen skills such as titration, qualitative analysis (QA) of cations and anions, tests for gases, and planning investigations.
Learn to present observations, tables, and graphs clearly, and draw sound conclusions from the data.
Detailed feedback on observations and conclusions helps students spot errors and refine their practical technique before the school lab test and the O Level practical.
