What is the difference between the two Advanced Practical Skills paper options?
These two Advanced Practical Skills papers are equivalent in every respect, except that they will contain different questions. Students should be prepared in exactly the same way whichever of these papers they are to be entered for.
The practical papers will be timetabled on different days. We anticipate that schools will decide which paper to enter their students for, based on the number of students and the laboratory resources available. They can either:
- enter all of their students for the same practical paper (it does not matter which one, but the school will need to have sufficient laboratory space and resources to accommodate all of their students) or
- enter half of their students for one paper and the other half for the other (which means that the laboratories only have to be able to accommodate half of the students on any one day, but which means that the laboratories will be in use for two days rather than one).
Do Cambridge supply chemicals for Chemistry practical examinations?
We are not a chemical supplier and do not have the necessary international permits to supply such materials. It is therefore not possible to order chemicals from Cambridge.
The following UK suppliers have shipped internationally in the past, and some Cambridge schools around the world have used them for their laboratory supplies:
If you have any other Cambridge schools locally, you may find it beneficial to contact them to ask how they source materials for practical examinations.

Hazard codes on confidential instructions for science syllabuses
To align with changes to global chemical labelling regulations1, we are updating the hazard codes which appear in the confidential instructions of Cambridge science practical exams. These changes have been in effect since 2016.
These changes will not affect candidates as hazard codes do not appear on question papers, nor are candidates expected to recall such information in their answers.
Please remind candidates that all substances in science practical exams should be treated with caution. ‘Hazard Data Sheets’ for materials used in the exams should be available from your chemical supplier. You should carry out appropriate risk assessments to ensure that local regulations relating to safety, first-aid and disposal of chemicals are followed.
We will update science syllabuses with the new hazard codes as each syllabus undergoes its regular review process. We will use the new hazard codes where relevant and in accordance with information provided by CLEAPSS2.
C = corrosive MH = moderate hazard
HH = health hazard T = acutely toxic
F = flammable O = oxidising
N = hazardous to the aquatic environment
