Why do JLPT N3 learners confuse きちんと with いらいら?

Both words occupy adjacent semantic territory, which is exactly why the JLPT uses them as distractors for each other on multiple-choice items. The fastest way to stop confusing them is to study them as a pair, write a one-sentence contrast in your own words, and drill the pair specifically rather than each word in isolation.

Is きちんと or いらいら more common on JLPT N3?

Both appear in the JLPT N3 curriculum and either may show up on a given exam. Don't try to predict which one the test will choose — learn to distinguish them and you'll be safe regardless. Both belong to the General Verbs (1) theme of N3 vocabulary.
