I took the N2 for fun in solidarity with @NicoleRauch (I passed N2 3 years ago and N1 2,5 years ago)
I missed one vocab question and one reading question.
Question 14
I picked 未 instead of 非. I think I read it as 未公開 instead of 非公式, oh well.
Question 71
I picked
1 どんな研究であっても、役に立つ新しい発見につなげられるから
The correct answer was
2 どんなことでも、自分の研究に役立つものがあるかもしれないから
The responses seem really similar to me, so I decided to ask a Japanese friend, and he also thought that 1 was the correct answer 
So even though the JLPT says it’s wrong, knowing that a Japanese person chose the same answer as me puts me at ease 
It’s only played once in the test; they don’t pause the audio or anything. Although there is a 〜20 second break after one of the questions where they play some relaxing music (lol)
I agree with your translation:
Sister: “I’m going to have dinner with my friends tonight.”
Brother: “Okay. If it looks like it’s gonna take until after 9 pm, I’ll come pick you up (at the station or the restaurant), so call me”
, but I think you’ve got it? As in, “If it gets past 9, I’m going to come meet you/pick you up (because I don’t want you to be out by yourself that late), so call me”
It was really difficult to get the numbers to add up sometimes, so take the weighted scores with a grain of salt
it might help people get a more accurate idea of their scores
A combination of finding it difficult to identify all of the all hiragana words and the fact that I’ve never really made an effort to study N4 vocab (I guess it would be too much to expect that it would all be vocab I would have picked up from reading shonen manga haha) means that’s not all that shocking. Surprisingly, what I expected would be the most difficult section for me (Listening) I turned out to find the easiest. I pretty much only dropped points on questions where I knew that I’d zoned out and stopped paying attention 
When I took the N3 in Japan in 2016 I thought listening would be my weak point (I was level 25 on WK and hadn’t really immersed in any content), but the listening portion turned out to be extremely easy and I managed to get 59/60 on it
Does that change in N2/N1? Do you need a meticulous knowledge of the grammar rules (‘cannot be used to express hope, intention or inducement’ and the like) to do well on the grammar section?
Though going through a 5000 card tango deck on Anki in time might be a bit of a slog.
