I went to math high school which was the most prestigious one in Russia at the time. Most of math class graduates would go to study math at the uni, and for the first year would be far ahead of their coursemates — but then would be hit by the sudden need to actually study the material and prepare for the exams like a wall of bricks.

In other words, the university was terrible at pacing the material, and the high school could only salvage the first year. Very common at university.
