After installing LockDown Browser, read the tips below and try it with the practice test in your course or the one in the SCCOnline Course Orientation class in D2L.

Before Taking an Online Test

  1. Exit out of any other programs that are running on your computer and reboot your computer. This clears your computer’s memory making it less likely to lock up or crash while taking a test.
  2. Use a wired Internet connection for the best reliability. Poor network connections can cause tests to lock up or answers not to be recorded.
  3. If you choose a wireless connection (wifi or cellular hotspot), check your signal strength before starting. It should be good or excellent. If not, find a location with a better signal.
  4. Tests must be taken in one sitting, so make sure you have enough time to complete the test before starting it. You cannot start the test and then change your mind or pause the test.

Taking a Test with LockDown Browser

  1. Log into D2L with your normal web browser, select your course, and navigate to the test.
  2. Read the test instructions carefully, noting the time limits. You can back out if you’re not ready to begin.
  3. Click Launch LockDown Browser to begin the test. Your web browser may ask permission to open LockDown Browser. Select Yes or Allow.
  4. Wait a moment while LockDown Browser starts up and the test is set up. This can take up to a minute.
  5. Once the test appears, the countdown clock will start.
  6. Answer each question, and click Save Answer. Saving answers helps preserve your work in case of an Internet or computer problem.
  7. When completed, click Submit Quiz.

Can I use an iPad?

Maybe. Your instructor can decide whether to allow iPad testing. There are some test options that do not work well on the iPad. This is one of the reasons why we require online students have access to a Windows or Mac computer.

Can I use an Android device or a Chromebook?

No. Respondus doesn’t currently offer versions for these systems, but we have indicated to the company that we would like to see them support Android and Chromebooks.


SCCOnline will try to assist students with technical problems, but cannot extend test deadlines. Only course instructors can do this.

Please take advantage of the practice test in your course or the practice test in the SCCOnline Orientation to make sure that you can install and successfully use LockDown Browser prior to a graded test. We do not have staff in the office over the weekends.
