Building on A2
You know three futures — B1 adds four uses
You know going to (plans), the present continuous (arrangements) and will (predictions). At B1 you add timetables, time clauses, quick decisions and plans that changed.
The film starts at 8.
A timetable → present simple.
I'll call you when I arrive.
A time clause → present after when.
Timetables

Use it for transport, shops, films, school terms — not for your personal plans.
