I'm hoping it won't be twice a year, just a little excessive if you ask me. I can think of better things to do with my free time, like oh I don't know, bang my head against a wall. That's pretty fun.
Biannual: occurring twice a year, at least occurring to Merriam-Webster.
biannual - Definition from the Merriam-Webster Online Dictionary.
If you did it last year it won't count. It's the same course but they have added a test at the end in addition to the questions at the end of each section. Very similar questions, but come one, "What does the red placard mean?" Then it shows you the placard and what is written on it. oh well.
