Stop Making Careless Mistakes on JLPT N3/N2: Fix your 3 checkpoints — 「主語」(subject), 「時制」(tense), and 「条件」(condition)

“I know it when I see the answer, so why do I still get it wrong on the real test?”

Careless mistakes do not happen because you lack concentration. In many cases, the real reason is simply that the 「チェック項目」(checkpoints) you should confirm are not yet fixed in your mind.

Instead of worrying about everything, build the habit of checking only these three points.

1. 「主語」チェック (subject check): 誰が、何が

Who did it? What is the sentence about?

In Japanese, the subject is often omitted, so test questions frequently include choices that switch the person or thing performing the action.

「誰が」(who) did the action? Or 「何について」(about what) is the sentence talking? Just pointing this out to yourself can eliminate many wrong choices immediately.

2. 「時制」チェック (tense check): 過去、現在、未来

Past, present, or future?

Even if the content looks correct, a choice with the wrong tense is still incorrect.

Is it 「すでに終わったこと」(something that has already finished)? Or 「これからすること」(something that will happen later)? Simply making a habit of marking 「時制」(tense) forms such as タ形 and ル形 can dramatically improve your accuracy in content-matching questions.

3. 「条件」チェック (condition check): ~なら、~ても、~場合

If, even if, in the case of...

「~したとき」(when something happened) and 「~したなら」(if something happened) do not have the same premise.

If you overlook expressions that set conditions, you can easily be trapped by an option that looks correct at first glance. When you see 接続助詞 (connecting particles) or 文型 (grammar patterns) that show conditions, treat that point as the branching point of a trap.

まとめ (Summary): 3つのチェックで十分

Three checks are enough.

If you try to confirm too many points, you may only become more confused, and your answering speed will drop.

「主語」(subject), 「時制」(tense), and 「条件」(condition). If these three become fixed checkpoints for you, you will save mental energy and choose the correct answer more accurately.
