Actually he was under the range by a bit.
The reason I say so is because A: What counts as studying japanese doesn’t always count as studying for the JLPT. B: Some people can get to that level much faster or slower depending on what they study and how well they learn.
The you can study for X amount of time for the N5, but any higher level knowledge you gained wont be of much use. I dont think anyone should base their studies around max score/time put in on each test. To then gauge the rate of your improvement by the time it takes to achieve certain scores on that test makes no sense.
Also as jpr said, hours are just time, not a measure of how much you actually have learned. An hour can do different things to progress your studies depending on the person. I like that they added the range as a guideline for what you can expect, but its not good to judge your progress. There is no set level that you should acquire in any amount of time.
Agreed. He actually has probably spent more time studying than me, but some of the things he said I just didnt agree with.
