My Expectation For Digital World

My expectation for digital world is to get about a 90 average every marking period. I expect Mrs.Ramirez to give out at least 3 projects. I expect to be really creative in the projects I receive. I expect to learn many things this term on digital world. I expect myself to be a great student and not miss any of my homework. Also finishing all my works on time/due date.
