Help needed please. When I log into the test for chapter 1 e1 the “ad page” is static on the right but the test page only half appears. I have to keep scrolling over to click next. And, when I get to the final question in the quiz I cannot drag and drop the page keeps moving instead if moving the jigsaw items I want to match up. Is anyone else experiencing this? Can this be resolved? And can you explain how I view the test page in full screen mode as I cannot see an icon to enlarge it. I am accessing this site on my iPad.
