The disc was very good. Don't think i would have done as well as i think ive done without it. Just got to wait on my results now. The s/d/t questions i found really helpful to keep practicing on. As i couldnt find anything on the internet that does s/d/t in the same way that they do. I improved alot on my diagraming, spatial reasoning, and compass headings too with the disc. Hope this helps anyone who is thinking about buying it. I think it is a bit of a rip off really but it is worth it if your a bit rusty in some areas and want to practice. You can buy it from this website
