Grade school level, not a "college course"

Since these courses bill themselves as being "college level" we felt obliged to weigh in. This one is nowhere near college level, which may be ok if you're looking to get kids interested, but for anyone beyond middle school or those looking for depth you will be disappointed. A lot of time spent looking at the telescopes and their history, all look-at and no substance about how-it-works. The production values and the visuals are nice, so it may find use as a family entertainment alternative to the cultural garbage out there. But as a college level course, nope. If you must try it used, not worth the steep price the vendor sets. Read more
