Booksmart and common sense do not go hand in hand at all. I know many people who are considered genius level IQ but lack the common sense to get in out of the rain.

My sister is one of those people who could walk in without studying and ace any test you gave her but a lot of times her street sense or common sense was severely lacking. Not talking shit about her at all but it has been proven time and again that if you are strong in a certain area you usually are equally lacking in another area.

Good example is people who are good at math usually lack in english skills or writing and vice versa.
