My Training tab doesn't work. I need to take the test. How can I fix this?

Let's work together in resolving this issue with your training tab screen in freeze, votienchuong25102001. I've got some troubleshooting steps for you to perform so you can get back to taking the test for your training. 

First, let's log in to your QuickBooks Online (QBO) account using a private or incognito browser to determine if this is a browser-related issue. This mode allows you to use the most recent version of the webpage without storing data that might interfere with display issues and cause the page to freeze. Here are the shortcut keys for accessing incognito mode: 

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N
   

If this resolves the issue, return to your regular browser and clear the cache to delete any temporarily stored files and browsing history. Over time, accumulated data can cause corruption; however, removing it should fix the problem. You may also want to use a supported, up-to-date browser to rule out any browser-related issues. 

In addition, you'll want to take a look at this US article that functions similarly in other regions if you wish to give feedback on exam questions and answers: QuickBooks ProAdvisor Program member guide for brand use.
