Lessons are paid for in blocks of five at the office, or singly in cash at the start of the hour. A block is cheaper and it does not expire, so a block bought before Ramadan is still a block in August.
The office is open whenever lessons are running, which means early mornings and evenings rather than the middle of the day. Somebody is there to print your record, take a block payment or talk about the test.
What the office cannot do is arrange your test. That is done in your own name with the transport authority and we will show you how.
