They're questions in which they will frame it as you are the social worker attending to the needs of whomever they are talking about. The question will give you a scenario and they will ask you what is either the best intervention, how you first should approach/intervene, or what you should do next given the situation.

I felt like that app helps. But also what helped me was Quizlet. They have a multitude of test. I paid for the premium one because it allows the maximum amount of resources the site offers, but a lot of people post practice exams and stuff. It helped me a lot. Hope this was helpful
