My school bought it for us recently, I’m in year 13 so very late in the game. I think if you’re in year 13 definitely not worth it. If you are in year 12 or before currently and have the financial means to do so, it absolutely is, it is nothing revolutionary you could get the same thing from watching videos and doing Quizlet/PMT BUT it is all in one place, efficient and guarantees money back if you don’t get an A/A* (under the rule that you’ve been consistent and have a certain amount of points on the website from using it regularly)
