MyLab Lessons are simulations of Microsoft Office that run in your browser. The assignments are designed to teach you how to perform tasks and then assess if you are able to complete them successfully on your own. You are graded based on how many questions you complete correctly.
MyLab Extra Credit Projects and Participation Projects are projects you complete in the real Excel, Access, Word, or PowerPoint applications and then submit to MyLab IT. The projects are automatically graded by MyLab IT. The MyLab Extra Credit Projects are optional and earn extra credit, while the Participation Projects are required.
