Straighterline Biology Book - edition?

[cookderosa]

For open book final exams at Straighterline, you have to be using the same version/edition as the course.
Otherwise, you are not supposed to be using a different version during the open book final.
If your son is going for it, I suggest using the current version you've got already.

I haven't decided, it may be up for later this year still. I'm confused by something you said- since it's not open book, his version won't matter (got that) but on open book exams the edition has to match? Wow, that's strict!?

Also, what did you mean that you suggest using the current version I've already got. Do you mean use the version I've got or the current version? (my version is ed 12, current version is 14)
