How saving works
The count shows questions with a correct latest check, not how many you visited. Skipping or opening a walkthrough does not raise it. Answers and your place save in this browser only; another device, browser, or link may have a separate notebook. Clearing browser data removes saved work. A later wrong check lowers the correct count. This is practice, not a grade.
Start with the main idea. One round, 8 questions in order. You can skip or pause. Check as you go. Open Walkthrough for help with this question, or open the solution key for the whole round.
Print this page for the round you have selected. Practice prints questions and working space. The solution key prints steps and answers.
