This Time
Next Time
noun
In the now occurrence you'll learn your kanji, no? This word means this time. Despite being "this time" it has the feeling of next time, though. It's like saying "okay, this time we'll get it" where "this time" really means "next time," making it a little bit different from 今回.
こんど
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
じゃあ、やっぱり今度にしよう。
Okay, then let’s do it next time.
今度は本当に本気の本気で日本ごをべんきょうします！
I'm really, really serious about studying Japanese this time.
今度俺がお前を泣かせる時は、嬉し泣きだ。
