you can count up to 2 for college honors credit i believe.
you register for them just like any other class. and you'll learn how to register for classes during orientation.
i've actually had to purchase books or course readers for my fiat luxes. i felt like they were a waste of money for a 1-unit course.
i took several fiat luxes during my freshman year and they vary in quality. the first one i took was "intro to negotiation" and it was a really good one!!! so i kept taking more thinking the other fiat luxes would be that great, but some were mediocre and some were just boring.
