Draft dodging was endemic. I knew a fellow, a teacher and biologist. To have at least two jobs was quite normal. He worked as a biologist for the government but of course could not live on his salary. His family were reasonably well off. He had been to New Zealand to continue his studies. In fact they owned a second house that they had rented. Such was the way of life in Saigon that the person who rented their second house had built an extra floor on it which he sub-let without their authority. When taken to court the case was thrown out as the party that had rented the house knew a more powerful judge. Anyway this young fellow had caught TB and had lost a lung. As such he was exempt from military service. However every year he had to have a medical examination to prove he was still unfit for military service. Perhaps the authorities thought lungs could grow again or something.
The Faculty of Law was the only faculty that did not require any entrance qualifications and the first year was terribly overcrowded. The exams at the end of this year were almost impossible to pass though. So far as I can remember Saigon was the only university in the country. The old imperial city of Hue had had the most prestigious one but it had long since been closed.
When I had arrived in Vietnam most of the educated older generation spoke French. It was a language also understood in a limited degree in some areas of commerce etc. There was now a desire to learn English as that opened up the possibility of going to The United States, Australia and New Zealand.
