Assignments and quizzes might reset, but the completion certificate will not. Hence, you can try out and play around with the new material without worries.
Hello! I cannot reach my old assignments. It says that I have to Upgrade and purchase a subscription to unlock my materials. But I already have a subscription, so when I click on the upgrade button, it enters my account and then the same message is active: “Purchase a subscription to unlock this item.” How can I reach my notebooks that had been previously graded? Thanks for the answer.
