Why do JLPT N5 learners confuse 零 with 一?

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 零 or 一 more common on JLPT N5?

Both appear in the JLPT N5 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 Numbers & Counters theme of N5 vocabulary.
