Why do JLPT N5 learners confuse 暗い with 低い?

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 暗い or 低い 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 Daily Life Nouns theme of N5 vocabulary.
