Should I drop french for gcse, to learn japanese instead?

Question:

I have three years to GCSE, so I think thats ample time! But, if I drop french I have more time to study japanese on my own. What do you think?

Answer:

Drop actual classes by a serious teacher so you can spend more time on Rosetta Stone? Doesn't sound like a smart thing to do...

Besides, France is just across the Channel for you, do you have any indication you'll be needing japanese?
