Paper 5 practical roadmap for Combined Science candidates who want biology-specific support in microscopy, food tests, and data interpretation.
Last updated: 2026-02-28
This page is for O-Level Combined Science candidates who want targeted practical preparation in Science (Biology), with single-science lab blocks instead of mixed-theory classes.
The practical component appears in Science (Physics, Biology) 5086 and Science (Chemistry, Biology) 5087. Lessons are run as focused science (biology) sessions so students can choose specific modules when budgeting or catching up.
If you are deciding between components first, start with the O-Level Combined Science practical hub to compare Physics, Chemistry, and Biology practical tracks.
Stay on this page for Combined Science Paper 5 in Science (Biology). Switch routes if you are taking another component or a pure-science practical instead.
| Paper | Duration | Marks / weighting | Focus |
|---|---|---|---|
| Paper 5 Practical | 1 h 30 min | 30 marks (15% of grade) | Paper 5 practical routines covering planning, observations, biological drawings, and analysis in combined-science contexts. |
| Area | Combined Science | Pure Science |
|---|---|---|
| Assessment load | Paper 5 practical: 1 h 30 min, 30 marks, 15% of final grade. | Paper 3 practical: 1 h 50 min, 40 marks, 20% of final grade. |
| Practical coverage | Uses combined-science practical contexts with focused microscope, food-test, osmosis, and planning routines. | Pure 6093 has broader paper demands and practical breadth, though key skill strands still overlap. |
| Session design at Eclat | Runs as standalone Science (Biology) practical blocks for candidates selecting modules by need and budget. | Built around pure-Biology practical planning for the full 6093 Paper 3 route. |

Other labs, such as PB11-PB12, are also available for those who want further training or as mock exams.
Sessions run in dedicated lab venues with fixed practical blocks for O-Level preparation.
SGD 150 Per 2-Hour Session

This page is for Combined Science candidates taking the biology component in 5086 or 5087. Pure-Biology 6093 candidates should use the pure practical page.
Yes. Science (Biology) sessions are run as dedicated practical blocks, so candidates can focus on biology practicals without mixing all sciences in one lesson.
Key practical skills overlap, but assessment weighting, duration, and paper format differ between combined and pure pathways.
Yes. Candidates can start with selected modules (for example microscopy or planning-heavy sessions) and then add mock practical blocks later.
