1. Never practising on a CBT screen
Students study from photocopies for months, then meet the exam interface for the first time under a running clock. Minutes disappear to the question navigator instead of to Japanese.
Fix: Take at least five full-length mock tests on an interface that mirrors the real CBT layout before your exam date.
2. Treating listening as revision, not practice
JFT listening audio plays once. Students who prepare by pausing and replaying build comprehension, not exam listening.
Fix: Practise listening the way it is tested — single play, no pause, answer immediately. Twenty minutes daily beats two hours weekly.
3. Underestimating the 80% pass mark
200 out of 250 leaves almost no margin. A student who is 'mostly fine' across all sections still lands near 180.
Fix: Set 215 as your practice target, not 200. Build the buffer before exam nerves eat it.
4. No feedback loop
Without section-level data you revise what feels comfortable, which is usually what you are already good at.
Fix: After every mock, read the weak-point report and spend the next three days only on the lowest-scoring section.
5. Cramming vocabulary, ignoring situations
JFT-Basic tests whether you can act in a situation — asking a supervisor for time off, understanding a delivery notice — not whether you can recite word lists.
Fix: Study vocabulary inside conversations and workplace scenarios rather than as isolated flashcards.
Every one of these is a preparation problem, not a talent problem. Start with a free diagnostic mock test and find out which of the five is costing you the most points.
