This course meets entirely online with no scheduled meeting times. Students may have to purchase physical and/or electronic books and/or other course materials. Course content is delivered through video recordings that students may access on demand through Canvas. For hands-on lab experience in this course, students will construct and test basic circuits at home (BRCC ships all materials directly to the student if outside of the college's service area). The course has proctored assessments and requires a webcam. These assessments are administered at the BRCC Testing Center or your local community college testing center if you live outside the BRCC service area. All assessments must be taken at a community college testing center, no exceptions.
