iPad Audio Issue 
注意：Apple iPads目前存在已知的音频录制和播放问题。这个问题发生在考试者播放录制的音频时。在播放过程中，音量非常低，可能无法被考试者听到。音频是以其适当的音量录制的，只是在考试者的设备上播放时减小了。管理员可以通过访问教师/管理员报告访问来检查录音质量。
建议的策略：让考生在不同的设备上完成口语部分是最好的选择。如果这不可能，指导考生在录音时使用附带的麦克风大声说话，然后在播放音频时将音量调至最高。提醒考生在完成测试的口语部分后，将音量调低。
Browser Permissions and Settings
Before testing, make sure:
- Cookies and JavaScript: Confirm that they have not been disabled.
- Managed devices: IT staff should confirm that browser or device policies do not block microphone or camera access.
- Browser window: Open the assessment in a regular browser window. Incognito and Private Browsing modes are not supported.
安全准备
病毒检查
在个人设备上完成Avant评估之前，我们建议在该设备的操作系统上进行病毒检查。这是为了确保设备上没有可能破坏测试数据的恶意软件。
浏览器扩展
我们建议在测试期间禁用Grammarly浏览器扩展，因为它会干扰虚拟键盘。也可能有其他扩展可能会造成干扰，禁用所有扩展可能会有所帮助。
