yea i saw, but u can see that both variants are in the time table.
So 1 school may take variant 1 and the other variant 2, the timetable will be different only for schools.
No man. If one country has multiple variants, there would be no point having variants at all.
Suppose I'm in China, where, according to you, follows variant 1 and 2. I'm doing 2
Suppose my friend is in the middle east, they're following variants 3 and 2. He too, is doing 2. Now, I can call him up and leak things.
^^So to avoid this, particular zones have the same variant.
Having multiple variants in the same country is practically futile.
