I managed to do self-study up until reaching mid level study, around NLPT N3. At that point, Japanese to English direct translation gets quite difficult. For new learners though, the sentence structure is so alien to English speakers it can be baffling, but one day it'll fall into place. There are patterns, just not English ones. The usage of particle markers in particular was a stumbling block for me.
I studied the Japanese for Busy People text first, and could do so much of it at the end, but still didn't comprehend the how and why. I was just parroting it. A year later I reviewed it and it was like child's play. Of course a tutor is good, but their advice may not sink in very well until you are more used to the language. Kind of like explaining how to play a video game before you play it, until you are actually playing it, it can go over your head.
