To add to WGW's second point, I found it useful during the planning stage to write seperate paragraphs for what done, how done and results, then to stitch them together at the end. This ensures you don't forget to put down anything you were asked for.
For determination, just find a project you undertook and explain how you stuck with it, getting help where needed, to get the result you set out to achieve. Project can be as mundane as you like, it's how you did it that counts.
Good luck with the verbal reasoning test!
