The tests from 10 actual (7-18 I think) are INCREDIBLY difficult. They have some easy games (like songs + newstape, three corsages, firefighters schedule, etc) that are either basic linear or relatively easy grouping games. Some of them are damn near impossible to setup. I think the one with the runners and sponsors/doctor yamata is so difficult. but YES. The general consensus is that the games get easier after this.
The reading compis supposed to be easier on these tests though. I'm starting at 7 and working my way up the newest...I figure I can cement my knowledge of games by crushing the early ones as they get easier while easing into RC that gets more difficult
