次回はnext timeです。 今度はthis time と next time どちらも使います。 今度は近い未来について言うときに使います。 次回　 次回のクラスで会いましょう。see you in next class. 今度（今回） 今度はうまくやります。　I will make it this time. 　　　　 　　今度は私が払います。 I will may for you next time. Does it make sence?

Adding some more to what Satomi had mentioned, 今度 also means "sometime" as in "Let's hangout sometime!" = 「今度あそびましょう！」

Sorry, I doubled my comments but I cannot delete it somehow. ごめんなさい！
