I'm doing pretty well in Japanese this semester, I have an A thus far, but I didn't do as well as I'd have liked on my last test because I have a trouble with sentence formation, due to the particles. Since I really want to keep my A, since I'm teetering between a B+ and an A for this semester, I need to get sentence formation down for my final.

Can you guys help me out with basic Japanese particles and when they're used, and sentence examples? The particles I've learned are ga, ni, ho (o), ha (wa), de... I think that's just about all of them. With basic sentences like, say, sushi ho (o) tabemasu, I'm solid. But when you have longer sentences with a lot of stuff going on, I get confused

Thanks guys!
