Is it possible to book a lesson for today?
The answer is: it depends.
We show booking slots from 24 hours ahead of the current time. This gives tutors sufficient time to see the booking and prepare.
So normally it's not possible to take a lesson at very short notice, e.g. on the same day. However, you can message your tutor (via email/Skype) if you wish to check in case they have time.
If they're able to teach you, here's what you can do: 1) book a lesson slot for another day, 2) your tutor can reschedule it to the agreed time (as they don't have the 24h restriction).
Tip: to avoid any misunderstandings, when asking for the slot, be clear on the time zone you are referring to - yours or your tutor's.
P.S. this workaround does not apply to trial sessions.
