I was a student of Mathematics Department of St. Petersburg Imperial University in 1900-1913.
Visiting of the University was not necessary for students. We have established the timetable of visiting our classes ourselves. The students could not visit there university over the years. I had not practical classes on my Department of Mathematics in St. Petersburg.
It was very interesting to study at the Imperial University and I wanted to be a good mathematician.
