This single lesson serves as a ramp for students rusty or unfamiliar with Excel spreadsheets.
Students with prior experience can efficiently show proficiency on the pre-quiz and move on to other lessons.
Students with no spreadsheet background can use the beginner narrated lecture to follow click-by-click guidance to internalize the basics.
Intermediate students can watch a shorter narrated lecture covering the same exercises but with screenshots and commentary rather than click-by-click screencasts.
Additional Excel guidance appears as exercise solution tutorials for the finance, economics, and statistics lessons.
