...the good, the bad and the ugly preferrably in English not business / banking speak, please? Type slowly and use small words please! 
Right now, my sons have their savings in money market accounts, and some in CDs. A friend of the family just gave them a huge check and told me to invest it in a college account for them and even though I've been trying to get to the bottom line of the positives and negatives of these, I can't seem to find one simple enough to wrap my brain around.
Any advice or insight?
Thanks in advance!
