It's important you're able to complete the exam so you can get your certification. Depending on which section you're working on, once you complete the certification, you'll be notified that it's complete. If you're seeing that there are more questions to work on but you can't find them, I suggest clearing cache and cookies on your browser. This is a great way to clean your browser while eliminating minor display issues on the site. Here's an article that shows you how to do that: How to clear cache and cookies. If this doesn't work, I suggest using a private/incognito window to see if that works instead.
