Apply as an online Combined Science tutor- Starting from S$11 per hour
- Contract, flexible hours
- 100% online, from where you live

Online Combined Science tutor jobs are about helping a secondary student carry two sciences inside one subject and one grade. SEAB sets three pairings for the O-Level: Science (Physics, Chemistry) 5086, Science (Physics, Biology) 5087 and Science (Chemistry, Biology) 5088. Students taking it usually have a single weekly lesson to cover both halves, so the tutor who helps them most is the one who can see quickly which half is costing marks and plan the hour around it. We are looking for online tutors who can teach both disciplines of at least one pairing, keep the teaching inside the Combined scope, and explain a circuit, a mole calculation or a genetic cross clearly on a shared screen. You teach from home, wherever home is, to students in Singapore.
Why teach Combined Science online with Eduprime
- You work from where you live, on a laptop and a writing tablet, with lesson hours you choose around Singapore afternoons and evenings.
- The syllabus is fixed and well defined, so what you prepare for one student in a pairing serves the next.
- Combined Science students often lean hard on one science and neglect the other, and a tutor who balances the two sees marks move within a term.
- Students outside Singapore who follow the same syllabus also come to us, and as their numbers grow we may offer you learners abroad who need your pairing.
- After you join, our team handles matching each student to you and sets up the lesson arrangements, so your time goes into teaching.
The role
What you will do
- Split each lesson between the two sciences in the student's pairing, giving more time to the half that is losing marks.
- Read the student's school test papers and topical worksheets to find recurring errors in definitions, working and units.
- Keep the teaching inside the Combined Science scope, leaving out content that belongs only to the Pure syllabus.
- Draw and annotate circuit diagrams, particle models, reaction equations, food webs and genetic diagrams live on a shared whiteboard.
- Practise multiple-choice and structured questions, including questions built on data tables, graphs and practical set-ups.
- Keep the agreed weekly lesson time and give the student advance notice of any change.
- Every few weeks, write the student a short note on which practical and theory skills have improved.
What we are looking for
- You can teach both sciences of at least one Combined Science pairing (5086, 5087 or 5088) to O-Level standard.
- Strong A-Level or IB results in the relevant sciences, a science or engineering degree, or current undergraduate study in one.
- A working grasp of where the Combined syllabus stops and the Pure syllabus continues.
- Clear spoken and written English at a level suited to secondary students.
- Previous tutoring helps, and a first-time tutor with strong science results is welcome to apply.

Matching
A request for your science pairing, at a time you have open, brings a proposal from us with the student's level and school details, and we arrange the first lesson.
Teaching a pair of sciences in one online hour
Combined Science asks a secondary student to carry two sciences at once, usually physics with chemistry or chemistry with biology, inside the timetable space of a single subject. Each half moves quickly, so a student who misses a week of electricity may already be on to moles and equations before the gap shows up in a test. Your first online lessons are mostly about finding out which half is holding the grade down and which topics inside it never quite settled.
A useful way to open is a short warm-up on the screen: a handful of quick questions drawn from both sciences, answered live while you watch the working appear. Early in the lesson you can usually see whether the trouble is content, mathematical handling, or the way answers are phrased. From there the lesson tends to settle into one half per lesson, with a brief return to the other half near the end so neither science goes cold.
Over a few weeks you build a simple map with the student: topics that are secure, topics that need another pass, and topics still to come in school. That map becomes the plan you agree on together, and it is easy to keep in a shared document both of you can see between lessons.
Where Combined Science students usually lose marks
Most lost marks in this subject trace back to a small set of habits, and an online tutor who knows them can work on them directly. Physics questions often fall apart on units and rearranging formulae: a student knows that speed is distance over time but stalls when asked for time, or forgets to convert minutes to seconds. Chemistry slips tend to come from balancing equations, ionic equations and mole calculations, where one early mistake carries through every later line.
Biology answers lose marks in a different way. The content may be known, yet the answer misses the precise term an examiner looks for, such as naming diffusion without mentioning the concentration gradient, or describing enzymes without linking shape to function. Data questions across all three sciences ask students to read a graph, quote values with units and explain a trend, and a common slip is to describe the trend without explaining it.
Practical skills sit across the subject too: reading instruments, drawing results tables with correct headings, identifying variables and suggesting improvements to a method. These can be taught well on a screen with photos of apparatus, sample data sets and planning questions.
- Rearranging formulae and converting units before substituting
- Balancing chemical and ionic equations, then checking them atom by atom
- Writing biology answers with the exact keyword and the reason behind it
- Describing and then explaining a trend in a graph or table
Seeing and marking written science work through a screen
Science answers live in the working: a labelled diagram, a balanced equation, a calculation laid out line by line. Online, you need to see that working as it is written. Ask the student to write on paper under a camera or on a tablet you can both view, and have your own writing tool ready, whether a pen tablet, a shared whiteboard or a camera over your notepad, to model the method in the same space.
For homework, agree on one simple routine. The student photographs or scans completed questions and shares them before the next lesson, and you mark them with clear annotations on the image: a tick where the method holds, a short note where a step went missing. Open the next lesson by going through those marks together so corrections are made while the reasoning is still fresh.
Diagrams deserve their own attention. Circuit symbols, ray diagrams, apparatus set-ups and labelled cells are easy to get almost right. Drawing one together on the whiteboard, then asking the student to redraw it alone from memory, shows quickly what has really been learnt.
A steady call is part of good science teaching too: a quiet room, your camera at eye level, materials prepared and shared before the lesson starts, and a short written summary of what to practise sent at the end.
Following two sciences through the Secondary calendar
Secondary science follows a clear rhythm through the year, and your lessons shift with it. Early terms are for building understanding as new topics arrive in school, so the work is explanation, worked examples and short practice sets. Around class tests and weighted assessments the focus narrows to the topics being tested, and the end-of-year examinations bring a full review across both sciences.
For upper secondary students heading into national examinations, the later part of the year turns towards full papers, timing and answer technique. This is when marking structured and free-response answers carefully pays off most, because students learn how marks are awarded and where their answers fall short. The practical component also needs its share of attention before the written papers.
School holidays give room for something different: revisiting a weak topic from the start, consolidating a whole half of the subject, or getting ahead of the next term. A student away from home over the break can usually keep working with you on the call, and lesson times during holidays are simply agreed afresh with the learner.
Questions online Combined Science applicants often ask
Do I need to be strong in all three sciences? You should be confident in whichever pair a student takes. When you build your profile you choose the subjects and levels you offer, so state honestly which combinations you can teach well.
Can I teach Combined Science and the pure sciences side by side? Yes. The topics overlap closely, and offering both works well, since the skills of explaining a concept, modelling a calculation and marking a structured answer carry across. You set your own choices of subjects, levels and hours.
What if a student and I are not a good fit? Learners can ask for a different tutor at no cost, which keeps the arrangement comfortable for everyone and lets each student find the teaching style that suits them. You simply carry on with the students you work well with.
How do I keep the student engaged without a lab? Use clear images of apparatus, short demonstration videos, everyday examples such as a kettle, a battery or a rusting bicycle, and quick prediction questions before showing a result. Curiosity carries well through a screen when the questions are good.
Questions
Questions from applicants
Do I need to live in Singapore?
You can teach from wherever you live. The lessons are for students on the Singapore syllabus, so what matters is your science knowledge, a reliable setup and free hours that overlap Singapore afternoons and evenings.
Can I teach only one pairing?
Yes. Tell us which pairing you cover, and we match you with students taking that one. Many tutors start with a single pairing and add another once they are confident in both of its sciences.
Which students will I teach?
Mostly upper-secondary students in Singapore preparing for O-Level Combined Science. As requests from students abroad on the same syllabus grow, we may offer you some of those students too, depending on the pairing and hours they ask for.
How much will I be paid?
Pay is hourly, from the figure printed on this page, and each student's rate and the payment arrangement are settled with you before lessons start.
Do I need tutoring experience?
Experience is welcome and it is optional. Strong results in the sciences you would teach, clear explanations and dependable attendance count for a lot, and our team briefs you on each student before you start.
How are practical skills handled online?
You teach the thinking behind the practical work: reading apparatus diagrams, planning a fair test, handling readings and uncertainties, and drawing conclusions from a table or graph. Hands-on lab work stays with the student's school.
