Private Candidate Science Practicals Singapore 2026: The Complete Guide

TL;DR
Every private candidate sitting a GCE science subject with a practical paper should plan for supervised lab training and, if they have not sat the same subject before, must meet SEAB's practical-training rule at registration.
Many specialist centres use 4 basic + 2 exam-style sessions for O-Level and 4 basic + 4 exam-style sessions for A-Level.
Registration opens 7-20 April 2026. Start training by January at the latest - November of the prior year is better.

Who this guide is for

This is the central reference page for anyone sitting GCE science practicals in Singapore without access to a school lab:

• O-Level and A-Level retakers who left school and need lab access
• Homeschoolers preparing for national exams through self-directed study
• PEI (Private Education Institution) students whose school does not have a science lab
• International students in Singapore sitting GCE O-Levels or A-Levels as private candidates
• Parents helping their child navigate the practical training requirement

If you are looking for a specific subject, jump to the subject-by-subject practical guides below.

The practical requirement at a glance

SEAB requires private candidates to meet the practical rule for every science subject that includes a practical paper. If you have not sat the same subject before, you must be currently attending or will be attending supervised practical training that will be completed before the practical paper. You cannot skip, waive, or substitute the practical component.
