If your university provides access to Graduates First, they have practice verbal reasoning tests which I used to practice (they made me go from 29th to 90th percentile lol) and I think assessment day has it too. In terms of the SJT, I tried to make sure that I thought about prioritising the client, the most efficient way to get the task done to the highest quality, not just choosing the solution of making it harder for myself and so on. For the behavioural section, be honest to an extent obviously but keep in mind that they want to see a mix of teamwork, leadership, trying new tasks (but also not dismissive of repetitive/lower skilled tasks), working with people different to you, etc. I received an email saying that I had passed the test this morning so hopefully this advice helps
