As far as I know, Skillpipe is just a client, an application that facilitates the reading process. The training content along with the questionnaires and tests that you can access through the application belong to third-parties and can be only accessed by specific clients, depending on what they're learning and who's providing the teaching materials.
So, if you want to find the answer to your questionnaire, you should look for that specific questionnaire or the exact name of the course that you're studying. Mentioning only the name of the app that facilitates the test won't yield any useful results.
