Answers
1. What are the system requirements for USMLERx?
This site is optimized for computer systems with a minimum of Windows XP/ME or Mac OS 10.3, 256 MB RAM, Internet Explorer 6.0 or Firefox 1.0 or Safari 1.0, Macromedia Flash 7, a monitor with a minimum resolution of 1024 x 768 pixels, and a broadband Internet connection. Older computer systems may see slower performance. We currently do not support other computers, operating systems, and browsers such as Linux and Opera. To see if your computer system can run USMLERx, please do the free Test Drive.
2. How closely does the USMLERx test interface resemble what I'll see on test day?
USMLERx is a faithful simulation of the NBME's FRED interface. We have added buttons like "Pause" and "Suspend" as additional functionality for test preparation. These buttons will not be seen on the actual test.
3. What happens when my subscription runs out?
If you need more time on your USMLERx subscription, click the links "Need more time?" or "Subscribe" on the home page after logging in. You will be presented with option to renew a subscription for 15 days, 1 month or 3 months. Please note that you cannot extend a subscription after it has expired.
