[Harry Potter] I'm ambidextrous. Will learning to use two wands at the same time actually work and give me an added advantage?

Assuming you can even be matched for two different wands which is highly unlikely, you can't perform two different spells at the same time. The wands are only channels for your magic. You'd have to learn to cast spells at the same time  

In theory, you could learn to rapid fire, but you can do the same thing with one wand.
