N1 and N2 listening resources (+any advice? Going for N1)

Hi all, so I’m going for N1 this summer. I got N2 about 5 years ago and have somewhat lost my Japanese, been working hard on getting it back recently. Maybe the N1 goal isn’t realistic, but I’ll try anyway as it’s good for motivation. 

What I’m doing now:

  • Reading a 中学歴史教科書, I like it a lot and it’s really motivating for me, even though it might be slightly simple
  • N1&N2 grammar anki deck, N1 vocab deck, + my own deck for interesting stuff I come across
  • Very occasional manga reading and anime watching (I’ve never really read or watched much Japanese stuff…)

I think I should do more, especially listening to stuff that is N1 grade. Do you have any suggestions for podcasts or whatnot that are N1-N2 level? I’m interested in science, psychology, history, etc, but probably some news stuff and formal stuff would do me good as well. I prefer stuff on the lower level of N1 as I’m not all that confident yet and get instantly demotivated when I don’t understand half of what is said. 

Any suggestions and comments about any of the above is much appreciated!
