Most JFT-Basic candidates study alone, on a phone, in gaps between shifts. That works for vocabulary. It works badly for everything else.
A partner - one person, meeting twice a week for forty minutes - fixes two specific problems.
Problem one: you stop
The dropout rate for solo study is the real reason people do not pass. Not ability, not time: attrition in week five.
An appointment with another person is the cheapest known fix. You turn up because someone is waiting, and the weeks in which you would have quietly stopped become weeks in which you did forty minutes anyway. Staying consistent covers the rest of the machinery.
Problem two: you never speak or hear live Japanese
JFT-Basic does not test speaking. But the Conversation and Expression section tests whether set phrases are automatic, and nothing makes a phrase automatic faster than saying it to a person who replies.
What to do in the forty minutes
Do not sit and study silently together. That is solo study with company. Use the time for what requires two people:
Situation drills (15 minutes). One person reads a situation, the other responds with the line. Leaving before your manager. Being offered help. Arriving late. Asking for a break. Swap. The list in polite requests is a ready-made script.
Dictation (10 minutes). One reads a short sentence aloud, the other writes what they hear. This catches listening errors nothing else catches - the difference between ななじ and しちじ, or a missed negative.
Explain the errors (10 minutes). Each brings two questions they got wrong in the week and explains the trap to the other. Explaining is the strongest test of whether you actually understood it.
Set the week (5 minutes). What each will do before the next meeting. Specific: “chapter 6 vocabulary”, not “study more”.
Sit mocks separately, review together
Do not sit a mock together - it turns into copying, even with good intentions.
Sit our free exam demo separately during the week, then compare section breakdowns when you meet. Comparing two breakdowns is genuinely informative: if you are both weak in reading, it is the material; if only one of you is, it is the habit.
Choosing a partner
Pick someone at roughly your level and with a similar test date. A large gap makes one person a tutor, which is generous and unsustainable.
If nobody around you is studying for JFT-Basic, a study group in your own language works fine. The value is the appointment and the speaking practice, not their Japanese level.
And if you want the structure without arranging it yourself, that is what a class is for - see online versus in-person classes.
