Many congratulations to them, studying whilst you are working is not easy and the course they have completed is at a high level.
Still, having gained their qualifications, the future should be a whole lot brighter for them.
For those who may be interested, the rest of my photos can be found here.
PS I started to use flash and then abandoned it and used natural light instead. That was perhaps a mistake because some of the pictures suffer from motion blur. Still, at least I did not interrupt the proceedings too much by having a flash go off every couple of minutes.
