We had a variant of this system where I went to school. It was enjoyable as it yielded a lot of free time and autonomy (even if taking an above average number of classes) but it's hard to say whether it had any meaningful impact on overall student performance. My school district was also reasonably wealthy, so there weren't a lot of people failing out or performing very poorly to begin with.
