Can someone please explain to me about the scaled scoring please?

So I just received my test results for JLPT N5 and although it says I passed, when I look at the scores, it looks bad at a glance.

Language Knowledge & Reading – 63/120

Listening – 31/60

Total Score – 94/180

I think see that the reference information for each category (Vocabulary, Grammar, Reading) has an "A" underneath them. When I checked the results guidelines, it meant that I was able to answer at least 67% of the questions for each category correctly. That would mean that I at the very least would have 67% or more so correct overall.

I looked further in the guidelines about scaled scoring, and it's a bit confusing to me. Rather than showcase your raw score, you score is than measured based on the difficulty of the questions, so as to make sure that you get the fairest results, or something. Anyone that has more knowledge on this let me know please!
