Creating a question pool from the HackerEarth's Library

To create a question pool from HackerEarth's Library, follow these steps: 

1. Navigate to the test that you have created.
2. In the Test details section, click Questions.
3. In the section to which you want to add questions, click Choose from Library.
   
   Note: HackerEarth’s Library is chosen by default.
   
   
4. In the All levels list, select the level of difficulty. For example, Medium. 
   
   Important: The difficulty level and the maximum marks of all the questions in a section must be the same to ensure that the testing process is fair. If you add questions of varying difficulty levels to a question pool, then some candidates may get a test that has many questions of the difficulty level Hard, while others may get a test that has many questions of the difficulty levels Easy or Medium. This will not give you an accurate assessment of the candidate’s skills.
   
   
5. In the All Topics list, select the topic that you want to add questions from. For example, Java.
   
   Note: While there are no restrictions on the number of topics that you can select, we recommend that you select only one topic per question pool to ensure that you use this feature effectively.
   
   
6. Select the questions that you want to add to the question pool.
7. Click Add selected.

You have successfully created a question pool.
