Which tense is right?
Hello, I would like to know which tense is right, the following A or B, (or the other).
A： What you learn in school, though it has seemed useless then, sure helps you later.
B： What you learned in school, though it seemed useless then, sure will help you later.
The context is:
A teacher (or a grown-up) is talking to a little boy, who cannot find values in studying in school, like, "I was like you. But now I know that what I learned in school has really helped me"
