Ninety minutes, sixteen men, and about a third of it spent listening to somebody else recite.
People ask what an evening is like, usually because they are deciding whether to give up two evenings a week for sixteen weeks. It is a fair thing to want to know first.
It starts after the evening prayer, not at a round number on the clock, because the hour is placed between two prayers rather than across one. Latecomers arriving off a boat go into the nine o'clock group instead, which is why that group exists.
The first stretch is recitation. Each student recites what they prepared since the last session while the teacher follows and marks their page. If you are waiting your turn you are listening to somebody else, and that is not dead time: most of what a student here learns about pace and about where people slip comes from hearing fifteen other people do it.
Then the group works on what is coming next, together and out loud. Then the last twenty minutes are the teacher going back over whatever most of the room found hard, which is decided on the night rather than planned.
It is deliberately unhurried. A student reciting under pressure to get through a quantity makes mistakes that then have to be unlearned, and unlearning takes longer than doing it slowly would have.
What we do not do at any point is put a date on when you will finish. How much somebody takes on between sessions is agreed with their teacher and it varies enormously across one group of sixteen. Two men who started on the same evening two years ago are in completely different places and both are doing well.
