Why do JLPT N1 learners confuse 震わせる with 辿り着く?

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 震わせる or 辿り着く more common on JLPT N1?

Both appear in the JLPT N1 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 (9) theme of N1 vocabulary.

震わせる vs 辿り着く

Q: What's the difference between 震わせる and 辿り着く?

震わせる (ふるわせる) means "to be shaking, to be trembling" and 辿り着く (たどりつく) means "to grope along to; to struggle on to; to arrive somewhere after a struggle". Both describe states associated with struggle and physical exertion; one refers to the physical shaking (震わせる) caused by fatigue or effort, while the other refers to the arrival (辿り着く) after that struggle.

Why JLPT N1 learners mix up 震わせる (ふるわせる, “to be shaking, to be trembling”) and 辿り着く (たどりつく, “to grope along to; to struggle on to; to arrive somewhere after a struggle”).
