He did not know how to program at all.
The teachers were lazy and repeated the same exams and activities year after year. Too many students took the easy path and either copied the answers from previous years or would google some snippets.
Worst: teachers didn't care if the code would compile, they would grade the effort.
In the end students would pass the year with positive grades (public university) and my brother would graduate next year without knowing how to write code on his own.
I hope that not too many students follow that lazy path.
