Long after. When I was a student, I took a suburban train at 8:23 AM every morning to get from city to our campus. One-way journey took me almost two hours. That included Saturdays!

We usually had 4 pairs a day, each pair consisting of two hours. No Easter breaks, of course. Oral exams: you get 4 out of 5 if you answer two theoretical questions, including proofs. To get a 5, one needed to solve an extra-curricular problem.

And this hell lasted 5 years, not 3.

My average mark was 5.0.
