Additional Things to Know
When answering questions, you should assume that the direction of any current is the direction of flow of positive charge (conventional current).
Please note that this test reflects what is commonly taught in high school. Due to differences in high school classes, it’s likely that most students will find questions on topics they’re not familiar with. This is nothing to worry about. You do not have to get every question correct to receive the highest score (800) for the test. Many students do well despite not having studied every topic covered.
