Oh wow! I didn't know this!! (And I like Aiba the most out of all of them! ^^)

It's definitely possible, though. And if you know the hiragana, you also know how to say it. Speaking is far more necessary to survival than writing, I think! ^^ It might be considered semi-illiterate, but living in Japan and amongst Japanese people could slowly heal that, I think! ^^

Don't feel bad one bit. In the short time you have been studying, you have near expert grammar. That is a pretty unmatchable feat!!
