Yes.
I was graduated from high school in Slovakia 2 years ago. In my town (about 45,000 inhabitants, 12th largest in Slovakia) there are 11 high schools (with 50-1000 students).
I was actually attending 8-year grammar school - a special school that merges elementary and high school, allowing me to finish my studies 1 year sooner than standard education. This was intended to be for "smarter" kids. (It isn't.) However in terms of quality I think it is similar to most of the high schools.
Out of about 11 classes I've taken every year, only 7 actually required some effort to get an A.
Some teachers did not even care about "cheating" on the exams - it was pretty common for me to solve all variants in 20 minutes and then distribute it in the class.
At the beginning of the school year, we got about 20 textbooks chosen by Ministry of Education. Half of them were never used, some were 15 years old. We paid only for few textbooks.
Students were bored, teachers were bored. Only few took their job seriously, only one was doing more than required.
During the classes like Biology, Geography, Chemistry, History and Slovak literature, the teacher dictated what we should write. During the next class, one was chosen and graded based on how good he/she memorized the notes.
The more students the school have, the more money it gets. Every school keeps as many students as possible. Even if they do not pass the entry test.
The last year was by far the most wasted year of my life. Student chooses 4 subjects from about 9 possible for the state exams. We were however still obliged to take 12 subjects. All teachers stopped teaching the other subjects, because it "was not required for our state exams" and "gave us time to learn the important subjects". They were simply lazy. Sometimes they didn't even attend the class.
Today I remember almost nothing except Maths and English.
On the other hand, free WiFi. And a lot of time for personal projects.
