DS6 did Earth Science this year and it was a wonderful course. We will do Life Science next year. Like Kriston I already have Life Science subscription valid till December but we haven't started it yet and won't till September.

I hope the co-op will make it available throughout the year. I believe you could buy it 4 times per year. I would like to wait till December before renewing Life Science and/or purchasing something new. That way I may be able to use it longer.
