Are there any official answer keys for past JLPT exams?

Hi everyone!

I'm just wondering if there's any official website where you can find the answer keys for the latest JLPT exams. I'm not talking about mock tests, I'm talking about the official exams, like the one that took place last Sunday.

How are you supposed to know the questions you've got it right? I reckon you only get your score and if you passed or not, correct?

And I keep seeing people posting how the actual test was harder than any other mock up tests, só I'm wondering if there's an official site where you can see the real test and use it for studying.

Thank you!!
