My humble 2016 JLPT N3 thread

I've been using the Shinkanzen Master N3 grammar book and just making cards based on the exercises.
The format is a sentence with a missing phrase and then a few options to choose from on the front, and the complete sentence on the back.

Front:
あの子はここにかばんを（　　　）どこかへ行ってしまった。

置いている間------置いたついでに------置いたまま

Back:
あの子はここにかばんを置いたままどこかへ行ってしまった。

I settled on this format despite a few negatives I can see.
First, it's multiple choice which is generally considered a bad practice with SRS since it turns a production task (creating a sentence) with a recognition task (selecting the word that fits best).
Second, it suffers from the same problem that I've always had with sentence cards: the subject of the sentence tips me off to the answer. For example, with the sentence above I might see the "あの子はかばん" and think "Oh, this is the one about the bag. The answer is '置いたまま'." Where I might not be able to come up with the answer to another question about the same structure but about a different topic.

I'm okay with the first problem since I am explicitly studying for the JLPT and it uses multiple choice. The second one I can't find a way around, so I just live with it.
