Most courses in high school allow you to resubmit an assignment for additional credit. My AP biology course won't. The teacher even goes so far as to say she said this wasn't possible, but I never found it anywhere. Perhaps she just likes my score the way it is?
In contrast, my creative writing teacher says she'd be happy to have me revise my stories. Go figure. Why must teachers be so different?
Google seems to have allowed a lot of JS errors to creep into its services. Aren't they validating their code?
