How to Save Your Progress

You can save your progress in two ways.

  • If a lesson has NO quizzes you will see the button: “Mark complete” that is located under the article. Click this button to save your progress.
  • If a lesson HAS a quiz, then there will be NO “Mark complete” button. Your progress is saved when after taking a quiz, you click on the button “Click here to continue.” This button will be visible after the quiz.
  • Keep in mind that if you, after a quiz, ONLY click on the “view questions” button to check correct answers, your answers will NOT be saved.
  • So if you want to save the set of answers, after checking your answers, you should also click on the button “click here to continue”.

Your progress is indicated by the green dots and line. Here is the location of your progress indicators.

Where to begin with GED Prep

You should choose the subject that’s easiest for you. In general, the goal is to go through a series of small successes to develop confidence in your capabilities. We call this the principle of “small steps.” Ask yourself: what topics are easier for me: Math, Language, Science, or Social Studies? Most people choose the Language Test as their first exam. Check also this video for more details.

To open the speed control menu, tap on the gear icon in the lower right corner of the embedded player. Under the speed menu, you can select different values for playback speed:

0.5x–  0.5 times slower than normal speed
Normal-Default Speed

1.5x–  1.5 times faster than normal speed
2x– 2 times faster than normal speed

Note: Both video and audio will be adjusted for all speed preferences.

Speed can be adjusted at any time before and during playback. You can modify the playback speed by clicking the gear icon in the player

Speed controls can be also accessed on iPhone and Android phones.

How do I adjust the volume of a video. Solution to no audio

If the video plays but there is no sound, please check if the sound is turned up on the (Vimeo) video player. It might happen that at some point you turned down the volume on the player, then it will remain that volume on any Vimeo video you watch.
