I did and was very dissapointed that I wasted money on it. Everything was so buggy and riddled with mistakes.
With that being said, my scores were about 2-3 points lower than my actual results. This probably correlates with the 3-6 questions per section that were impossible to get right due to errors on the part of the creators.
Unless they have done some serious overhauls in the last 3 months, save your money and go with achiever/topscore. I guess the stand alone sections could be helpful for timing practice...but you will still find a frustratingly high amount of false information.
Good Luck
