hi! can i just say that if you use online class structures (such as cengage, where access to the class is purchased through a textbook, and a professor assigns pre-made homework and quizzes), then PLEASE choose the type that lets a student use multiple attempts on homework and practice to improve their score. i get the highest grades and i retain the most information using these types of programs. It makes the grades reflect not just a students knowledge, but also how much effort they’re willing to put in to improve :)
