Combined Science vs Triple Science

GCSE students may study Combined Science or separate sciences, often called Triple Science. This guide explains the difference in subject depth, grades and workload, and how to identify whether support is needed in Biology, Chemistry or Physics.

£1 First Lesson: £1 applies to the first one-to-one lesson only. Regular lessons then continue at the applicable standard rate. After the 14-day cooling-off period, cancellation requires 4 weeks’ written notice.

Direct answer

What is the difference between Combined Science and Triple Science?

Combined Science covers Biology, Chemistry and Physics but normally awards two GCSE grades. Triple Science, also called separate sciences, teaches Biology, Chemistry and Physics as three separate GCSEs and usually includes more content. The route available to a student depends on their school.

What this means

Both routes can support future Science study

Combined Science can still provide a route into A-Level sciences where the student meets the relevant sixth-form or college entry requirements. Triple Science usually covers more content, but the most suitable school route depends on the options available, the learner’s interests and workload.

  • Check whether the student is doing Combined Science or separate sciences.
  • Identify whether the main gaps are in Biology, Chemistry or Physics.
  • Match tutoring to the specific exam board and paper structure.
  • Balance ambition with workload and confidence.

How to approach it

A practical step-by-step approach

1

Confirm the school route

Check with the school whether the student is taking Combined Science or separate Biology, Chemistry and Physics GCSEs.

2

Identify the individual science need

Work out whether the main difficulty is in Biology, Chemistry, Physics, mathematical skills or practical-style questions.

3

Check the exam board and specification

Use the correct specification, past papers and mark schemes for the student’s course.

4

Review progress by subject area

Track progress separately across Biology, Chemistry and Physics rather than relying only on an overall Science impression.

Key considerations

What parents usually need to compare

Biology

Cells, organisation, infection and response, bioenergetics, homeostasis, inheritance and ecology.

Chemistry

Atomic structure, bonding, quantitative chemistry, chemical changes, energy changes, rates and organic chemistry.

Physics

Energy, electricity, particle model, atomic structure, forces, waves and magnetism.

How NLG can help

How NLG supports students studying GCSE Science

NLG does not tutor Combined Science as one single subject. If a student studies Combined Science at school, tutoring is booked as Biology, Chemistry or Physics according to the area where support is needed. Standard GCSE one-to-one tutoring costs £39.90 per 40-minute lesson.

  • One-to-one GCSE tutoring is booked as Biology, Chemistry or Physics.
  • The first one-to-one lesson costs £1, then standard GCSE pricing applies.
  • Tutor matching considers the learner’s science subject, exam board, current priorities and suitable tutor availability.
Important: Combined Science is an educational qualification discussed in this guide, not a separate NLG tutoring service. NLG Science tutoring is booked as Biology, Chemistry or Physics.

FAQ

Common questions

Triple Science usually includes more content because Biology, Chemistry and Physics are studied as three separate GCSEs. Whether it feels harder depends on the learner, the school programme and the amount of time available for each subject.

Often yes, provided the student meets the relevant sixth-form or college entry requirements. Entry requirements vary, so families should check the specific course they are considering.

No. NLG does not tutor Combined Science as one subject. Students who study Combined Science at school book tutoring as Biology, Chemistry or Physics according to the area where support is needed.

Yes, where suitable tutors are available. Biology, Chemistry and Physics are booked as separate tutoring subjects, so NLG can check an appropriate tutor match for each science required.

Standard GCSE Biology, Chemistry and Physics one-to-one tutoring costs £39.90 per 40-minute lesson. The first one-to-one lesson costs £1. After the 14-day cooling-off period, cancellation requires 4 weeks’ written notice.
