I'm first kind of confused about Ga and wO ... so I guess what I learned just went over my head so maybe you can reframe the idea of the two.. Because I went through the drills and I ended up just selecting wO as it produced an action word being done... but I didn't totally get it what the difference is for ga?
Also I've been learning a lot of yon nomi and I'm recognizing them for future use... but sense I finally got to Taking out the Kanji it's now going over them and how to use them.
So for example:
It uses the on yomi for the pronounciation. Does it ever not use on yomi and when it doesn't how do you determine the usage of the other available on yomi and kun yomi?
