Another way of booking a session with a tutor is through the weekly calendar where you can see all the available tutors on a given date at a given time. You can find it in the 1-1 sessions page.
Select a specific date and time and you will see all the tutors that are available for that slot.
In the next step, you will have to choose the topic you would like to go through in the session. You can either type a topic of your choice or choose a topic from your Syllabus. The tutor will see the topic you chose before the beginning of the session.
Once you've confirmed your booking, a page will show you details of your session.
