By European standards, its gun laws are permissive. It allows people to carry concealed weapons for the purpose of self-defense, and it is one of the few countries in the world — and the only one in Europe — that provide the constitutional right to bear arms. But exercising that right is contingent on the test. Czech lawmakers and gun owners say their national system dramatically increases the odds of responsible ownership. The rules also require a health clearance and a background check, and demand safe storage of weapons once they are purchased. In a country more populous than New York City, there were seven homicides using guns during all of last year. “We really have bad politics in many ways here — corruption. But something I am proud of is this law,” said Martin Fiser, 35, a weapons instructor. “It can be a model for the rest of the world.”
The test is obligatory for anybody who wants a weapon, including hunters, collectors, even someone inheriting a shotgun from a grandfather. The standards are high: The test consists of questions randomly drawn from a pool of 501 possible. Those trying to obtain the hardest-to-get license — for concealed carry — can miss no more than one question. The failure rate is around 40 percent.
Czech lawmakers say they have a luxury that Americans do not. Guns are not a politically fraught issue. About 1 in every 30 Czechs hold a gun permit. For most of the rest, the issue is rarely discussed. The constitutional right to bear arms was put in place only last year, not because of some popular groundswell, but because lawmakers liked the national laws as they stand and wanted to make sure E.U. initiatives passed in response to terrorist attacks wouldn’t jeopardize them. “Guns are valued by gun holders,” said Martin Cervicek, a senator and former president of the Czech police forces. “But they are not viewed as sacred.”
https://www.washingtonpost.com/world/20 ... -republic/The Czech national testing system was born in the vacuum of the 1989 Communist collapse. The Communists had decreed that guns could be licensed only to those proving capability. But in practice almost nobody aside from police and party apparatchiks had been able to get one. As the new Czech democracy tried to interpret that vague law, local police started conducting examinations. Within a few years, the system was formalized: a written and practical test, overseen by a government-appointed commissar. The country has regularly expanded the pool of possible questions for test-takers. The Czech Interior Ministry, which oversees the testing system, did not allow The Washington Post to sit in on tests. But it shared uncut videos of several testing sessions, which take place at gun centers across the country, generally in groups of 15 to 20 people.

California's Firearms Safety Certificate to purchase a firearm is 30 questions but it's not timed. I don't think it's difficult but CDF has more experience with it.
