The qualification

What is IGCSE Combined Science (0653)?

IGCSE Combined Science brings biology, chemistry and physics together in a single course, usually taken between ages 14 and 16. Cambridge offers it as syllabus 0653, with 33 topics in three sections. Students study all three sciences and earn one IGCSE grade.

That makes 0653 a single award. Cambridge Co-ordinated Sciences 0654 is a double award, with more topics, longer papers and two grades from A*A* to GG. The Pearson Edexcel Science Double Award, 4SD0, gives two grades, on the 9 to 1 scale.

According to the June 2025 results from Cambridge, 68.7% of IGCSE Combined Science entries got C or higher, and 22.4% earned an A*. Marks slip when a paper jumps from cells to circuits. Your tutor sets mixed questions until that feels normal.

Our approach

How lessons cover three sciences without the overload

Lessons are private and live, so the tutor can move between biology, chemistry and physics as your child needs. Here is how the weeks are organised.

One plan for all three sciences

Early lessons show which science, and which topics inside it, costs the most marks. The plan then shares time fairly, so a weak area in physics does not get lost behind stronger biology.

Matched to the right course

Tell us whether your child sits Cambridge 0653, Co-ordinated Sciences 0654 or Edexcel 4SD0. We match a tutor within 24 hours, and offer a free re-match if the fit is wrong.

Answers marked like the real exam

Each week includes real past questions, marked by the tutor against the official mark scheme. Short-answer theory rewards exact wording, so this is where that habit gets built.

Practical skills, even at home

Paper 5 and Paper 6 test planning, measuring and drawing conclusions. The tutor walks through past practical questions on the whiteboard, so the written method becomes second nature.

Revision that stays after class

Recordings of every session stay available to replay. Notes, flashcards and topic maps come too, making it easier to revise three sciences side by side before a mock.

Lesson times that fit your week

Lessons are booked in your own time zone, on school nights or weekends. Pay as you go, or pick a package. There is no lock-in.

How it starts

Four steps from enquiry to weekly lessons

1

Tell us the course

Send the syllabus code, Core or Extended, and the science that worries your child most.

2

Get a tutor in 24 hours

Within 24 hours we confirm a tutor familiar with the exact papers on your exam timetable.

3

Try a trial lesson

The first lesson costs AED 20 to 60, and there is no commitment to carry on.

Settle into a weekly plan

Lessons rotate through weak topics in each science, and a free re-match is there if you need it.

Compare options

How tutoring compares with other ways to revise

Students often start with a revision guide or a group class online. Here is how those options compare with one-to-one lessons on weak topics, marked answers and practical paper practice across three sciences.

How your tutor prepares each Cambridge 0653 paper

Each Cambridge candidate takes three papers, entered at Core or Extended: multiple choice, theory, then one practical paper. On the Edexcel Double Award route there are three two-hour papers, one per science.

Forty quick science questions

Questions jump between all three sciences. Your tutor runs short timed sets so your child learns to read each option carefully and keep a steady pace.

Switching between sciences

Moving from enzymes to electricity in one sitting trips many students up. Your tutor mixes topics in practice so each change of science feels routine.

Common questions

Combined Science questions from parents

Quick answers on awards, papers, exam boards, entry rules and fees.

Is Combined Science a single or double award?

Cambridge 0653 is a single award, so it gives one IGCSE grade. Cambridge Co-ordinated Sciences 0654 and the Edexcel Science Double Award 4SD0 are double awards, worth two IGCSE grades.

Which papers does Core or Extended mean?

On the Core route, students take Papers 1 and 3, with grades C to G open to them. The Extended route uses Papers 2 and 4 and opens A* to G. Both routes add Paper 5 or Paper 6.

Can my child take Combined Science with Biology?

Not in the same exam series. Cambridge does not allow 0653 alongside Biology 0610, Chemistry 0620, Physics 0625 or Co-ordinated Sciences 0654. Check the school's entry plan early.

How is the Edexcel Double Award assessed?

Students sit three untiered papers, one each for biology, chemistry and physics. Each lasts 2 hours and carries 110 marks. Grades run from 9 9 at the top down to 1 1.

Can my child study A-Level sciences afterwards?

Entry rules differ between schools and colleges, so ask the sixth form what grade it wants. Extended content and a strong grade give your child a firmer base for A-Level study.

What do Combined Science lessons cost?

Prices begin at AED 50 per hour and vary by tutor, and a trial is AED 20 to 60. Families can pay for each lesson separately or choose a package, and can stop whenever they like.
