Now we can try combining the two titles together:
"I'll do it later, after school!" אֶעֱשֶׂה אֶת זֶה אַחֵר כָּךְ, אַחֲרֵי בֵּית סֵפֶר!
And how would you say "I'll do it later, after I finish (graduate) school"?
Right,אֶעֱשֶׂה אֶת זֶה אַחֵר כָּךְ, אַחֲרֵי שֶׁאֲסַיֵּם בֵּיתִי סָפַר

Thinking about the practical applications of this phrase - on a personal level I wish you do not use it too much - that's a phrase of a typical procrastinator - אֶעֱשֶׂה אֶת זֶה אַחַר כָּךְ! ;)
And of course I hope that you do not say אֶעֱשֶׂה אֶת זֶה אַחַר כָּךְ about Hebrew!
Keep learning, and do it now! ;)
Yours,
