"Andi tidak sering belajar."

Translation: Andi does not often study.

I think the current translation is fine, but "Andi does not often study" should also be accepted

[Caitlin943300]

Yes agreed

I agree the sentence is not right, but I disagree with your offering. It should be "Andi does not study often.", but DL will mark this as incorrect.

Agree with the alternate translation suggested.
