A sample from this course
One topic, as StudyPath teaches it.
Objectives;
This topic focuses on the learning objectives of Nature of Matter II: understanding matter at a deeper level through atomic structure, bonding, states, and changes in matter. For examination purposes, you must know not only the facts but also the purpose of studying them—how they explain observable physical and chemical behaviour of materials.
What you get for ISC 221
Every topic above, split into sessions and dated against your exam.
Practice questions per session, with answers that explain themselves.
