The array of subjects covered on Saturday morning are magnificent and well worth the time spent watching. That includes adults seeking a "refresher" on subjects they learned some time ago. I would place coverage matter in the 6th through 8th grade span of learning.
It is hard to believe that the "CBS Dream Team" has not received recognition for these half hour presentations all ready. We came on to the Saturday series coincidentally while "randomly surfing the channels", but our extended family have now become avid followers.
Good Job CBS!!!
