When creating a new test, you can either allow us to automatically pick questions for you or you can create an empty test and choose the questions yourself.
Accessing Library
After you have created a test, open the test and go to the Questions section at the top of the page.
Once there, click the New Question dropdown and select Add From Library.
Picking a Question
You can either pick a question from our list of questions, or you can pick from your previous tests if you are trying to make a similar new test.
You can filter questions by programming language, question type, or difficulty level to quickly find the ones that best fit your test.
Close the library after you have added all the questions you need.
Note: You might want to change the Time Limit of the test as you see fit after this.
