Online Combined Science Tuition in Singapore: One-to-One and Small-Group Tutors for G2 and G3 Science
Combined Science is one subject built from two sciences, such as Science (Physics, Chemistry), with a separate paper for each, so students keep two sets of topics, formulae and practical skills going at once. onlinetuition.sg matches Sec 3 and Sec 4 students with Combined Science tutors for live online lessons, one-to-one or in small groups, at G2 or G3.

About Combined Science in the SEC
From 2027, the national exam at the end of secondary school is the Singapore-Cambridge Secondary Education Certificate (SEC), first taken by the cohort that entered Sec 1 in 2024. Combined Science comes as Science (Physics, Chemistry), Science (Physics, Biology) or Science (Chemistry, Biology), at G3 or G2. G3 Science keeps the papers and topics of O-Level Science (5086 to 5088), which students sat until 2026.
- G3 Science (K326, K327, K328)
- Paper 1: 40 multiple-choice questions on both sciences, 1 h (20%) · a structured and free-response paper for each science, 1 h 15 min each (32.5% each) · Paper 5: practical test, 1 h 30 min (15%)
- G3 structured papers
- Section A: compulsory structured questions worth 55 marks, the last worth 10 · Section B: a choice of one 10-mark question from two
- G3 practical test
- One or two questions on each science, including suggesting a change or extension to an experiment
- G2 Science (K223, K224, K225)
- For each science, a 20-question multiple-choice paper (20%) and a 30-mark structured paper (30%), sat together in one session of 1 h 15 min; no separate practical test
- Grades
- G3 from A1 to 9, as at O-Level · G2 from 1 to 6, as at N(A)-Level
- Results
- In January of the following year
At G2, about a tenth of the marks test experimental skills inside the written papers, and SEAB advises spending no more than 30 minutes on each multiple-choice paper.
Common Challenges Combined Science Students Face
Two Sets of Topics at Once
Students revise two sciences side by side, each with its own structured paper, vocabulary and way of setting out answers.
One Multiple-Choice Paper for Both
At G3, Paper 1 covers both sciences in 40 questions and one hour, so revision has to stay even across the two.
The 10-Mark Questions
The last question in Section A and the Section B choice carry 10 marks each, so longer answers need a clear plan.
The G3 Practical Test
An hour and a half on both sciences, with readings, observations and a suggested change to one experiment.
Experiment Skills Without a Practical at G2
G2 papers ask students to read scales, plot graphs and spot sources of error, all on paper.
Fewer Topics, Same Precision
Each science covers less than the Pure Science course, but answers still need exact terms, units and working.
How Our Online Combined Science Tutors Help
A Plan That Covers Both Sciences
Weekly lessons that keep both halves of the subject moving, with extra time on the one your child finds harder.
Section B Practice
Picking the better 10-mark question quickly, then planning and writing a full answer.
Equations and Units Drilled
Regular practice with the calculations in the sciences your child takes, until the steps become routine.
Practical Preparation
Tables, graphs, errors and improvements, for the G3 practical test and the experiment questions at G2.
Topical, Then Mixed, Revision
Topic by topic in Sec 3, then mixed papers across both sciences in the months before the SEC.
The Right Combination and Level
A tutor for your child's exact subject, from Science (Chemistry, Biology) at G2 to Science (Physics, Chemistry) at G3.
Combined Science Topics Covered by Our Tutors
Each Science subject takes two of the three sections below, in each syllabus's own words. The syllabuses don't split topics by school year.

- At G2 (13 topics)
- The G3 list without turning effect of forces, light, and magnetism and electromagnetism
Chemistry Section
- At G3 (12 topics)
- Experimental chemistry · the particulate nature of matter · chemical bonding and structure · chemical calculations · acid-base chemistry · qualitative analysis · redox chemistry · patterns in the Periodic Table · chemical energetics · rate of reactions · organic chemistry · maintaining air quality
- At G2 (9 topics)
- The G3 list without redox chemistry, chemical energetics and rate of reactions
Biology Section
- At G3 (12 topics)
- Cell structure and organisation · movement of substances · biological molecules · nutrition in humans · transport in humans · respiration in humans · infectious diseases in humans · nutrition and transport in flowering plants · organisms and their environment · molecular genetics · reproduction in humans · inheritance
- At G2 (8 topics)
- The first eight, from cell structure and organisation to nutrition and transport in flowering plants
G1 Science (K123)

Frequently Asked Questions About Combined Science Tuition
Thinking of Combined Science Tuition?
Is Combined Science a Lighter Load Than the Pure Sciences?
In content, yes: each science is half of one subject, and the Physics half, for example, has 16 topics against 20 in G3 Physics. The exam skills are the same, so precise answers and careful working still count.
Which Combined Science Subject Will My Child Take?
One of three pairs: Science (Physics, Chemistry), Science (Physics, Biology) or Science (Chemistry, Biology), at G3 or G2, depending on what your child's school offers.
Does G2 Science Have a Practical Exam?
Not a separate one. G2 Science tests experimental skills inside its written papers, for about 10% of the marks, while G3 Science has a practical test of 1 hour 30 minutes.
When Should My Child Start Combined Science Tuition?
Early in Sec 3 is a good time, while both sciences are new, or as soon as one of them starts to slip. Starting in Sec 4 still leaves time before the preliminary exams and the SEC.
Getting a Tutor
How Do I Request a Combined Science Tutor?
Use the free form above, where Combined Science is already ticked, and choose G2 or G3 if you know it. We aim to get back to you on WhatsApp within one working day.
Can One Tutor Teach Both Sciences?
Often, yes. Tell us the combination, and we'll look for a tutor who teaches both halves.
What If My Child Moves From G2 to G3 Science?
Let us know. The tutor can switch to the G3 syllabus and add practice for the practical test, or we can change the tutor if that suits better.
Lessons
How Are Combined Science Lessons Taught Online?
Live on Zoom with cameras on, with circuits, chemical equations or cell diagrams drawn on a shared screen or digital whiteboard as the tutor explains.
How Long Are the Lessons?
Most run for 1.5 or 2 hours, once a week at a fixed time.
What If My Child Misses a Lesson?
Let the tutor know directly. After a missed group lesson, your child can usually watch the class recording.
Others
How Much Does Combined Science Tuition Cost?
It depends on the level and class size, and we confirm the fee on WhatsApp before the first lesson.
Do You Charge Agency Fees?
No.
