"Philip desired popularity but could bring himself to make no advances to others. A fear of rebuff prevented him from affability, and he concealed his shyness, which was still intense, under a frigid taciturnity. He was going through the same experience as he had done at school, but here the freedom of the medical students' life made it possible for him to live a good deal by himself."

Interesting that there is no mention of study groups. They can provide very valuable informal testing. I think I learned more in study groups than I did in lectures.
