Description

1.5 Casting and Ranges of Values
#13 the answer should be 2 but is not one of the choices
#14 the answer is 5 but it marks it wrong

I've also had students say when they "check me" it show correct but that it doesn't update points (not sure if there's something I'm missing there to make it auto grade those). Thanks!
