Is it possible to pass N1 by the next test? What do I need to do to accomplish that?

So, I really must, need, want to pass N1 by the next test. I definitely have the drive, motivation and consistency to do it. Is it possible to do this? I haven't really tried studying for the test in years, and I don't know where I stand actually, What kinds of things should I be doing or resources to get to help me pass the next N1 test.

Right now I have N2, I have Kanji Kentei pre-2. I read a Japanese Intermidiate level novel a week. I look up the words and grammar I don't know and turn those into SRS to review.

I have lived in Japan for 20 years and my major is Japanese, but I haven't really pushed myself hard to gain the mastery to pass N1, but enough fooling around. I got to get this so I can get a better job and open more doors. At 40 I have wasted too much of my life partying and I have no one to blame buy myself.

Thank you for your suggestions and feedback.
