THIRD FORM
This introductory course will allow students to gain greater insight into the properties and behaviours of the materials in the world around them. If they choose to pursue this subject at the CSEC level this course will have covered most of the basic principles and is therefore a prerequisite for that course.
SBA skills will be developed during this time but no marks awarded can be used for CXC purposes when students enter for CSEC Chemistry.
