Why do JLPT N2 learners confuse 書留 with あいかわらず?

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 書留 or あいかわらず more common on JLPT N2?

Both appear in the JLPT N2 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 Adjectives (1) theme of N2 vocabulary.

書留 vs あいかわらず

Q: What's the difference between 書留 and あいかわらず?

書留 (かきとめ) means "writing down, putting on record, recording, making a note of, registration (of mail)" and あいかわらず (あいかわらず) means "as ever, as usual, the same". Both involve the concept of 'records.' 書留 refers to recording mail (registration), while あいかわらず describes an 'unchanging record' of state, potentially confusing the act of logging with the state of consistency.

Why JLPT N2 learners mix up 書留 (かきとめ, “writing down, putting on record, recording, making a note of, registration (of mail)”) and あいかわらず (あいかわらず, “as ever, as usual, the same”).
