Thinkscape automatically keeps track of the progress you’ve made through a module. The only things you need to make sure to save yourself are questions. To save your answer to a question you must click Submit before you move on to a different step or module. If you do not submit a question before moving on to a new step, your answer will not be saved.
When writing completing your lab report, you need to click either Save or Update after making changes to each text box to save what you’ve done. If you leave the lab report editing view without doing this, your changes won’t be saved.
