Changes in maturita topics

Today, Hanka and Klara came (after learning with Eki - our Biology teacher - for their maturita) that maturita topics rules had changed. When I asked Ms. Duskova, she just by the way admitted it. Before, it was possible to include two questions (e.g. in Math, one question could have been some Geometry, while the second some exponential equations solving) in one maturita topic. It's no longer possible (the only exception is the Czech language - there may be still one language and one literature question). Now one question = one topic. For me, of the four Maturita subjects just Math is affected. Still, it disturbs me.
The primary disadvantage is obvious - if you messed up one question before, you could compensate it in the second. Now, if you can't remember one question, you are doomed (i.e. you fail the maturita or have a very bad grade).
Now the second trouble is that we should have known the topics for sure since September. A lot of people already started elaborating the topics. Now, they'll have to do it again, or, at least, remake it, merge it, edit it...
It seems the rule isn't our school-made, but from the ministry, so it's not really very possible to argue with.
We'll have to grin and bear it this time. Fine. But it's about the principle. The rules, that should have applied since September, are changed in November. Now if it concerned just my personal life and my free decisions, it'd be OK. I'm used to that nothing is certain nowadays and no principles hold. We may envy our ancestors, for having the dogmas set both by religion and by their rulers and not having to think. Or we may be glad for the possibility of nearly unrestrained free thinking. I'm the second one.
Yet this is not the case of just my personal decisions. I have to do the maturita in order to get to the university. Maybe universities would require even without the obligation (still, I think it's unlikely), but now it is obliged. You see, I'm distrustful just of the thought of the (de facto) mandated maturita.
(OK, I don't have to moan that much, in next years "new maturita" will be enacted and that one is even more centralized (i.e. one exam for all the schools, while today schools are quite free in making the topics).
But back to the point - I have to do the maturita under some rules. But the above mention incident shows that I can't even be certain what are those dictated rules. I know it for now; but then it can change every time, e.g. one day before the exam. OK, I hope it won't be that way, it's surely rather improbable. But who knows. The bureaucrats in the ministry don't have to care about the students (nor anyone else) when making "the better world".
