What is the best mindset to have to get gains on this test?

Moving from bracket to bracket (140 to 150 to 160 to 170...)?

Consensus on the board is curriculum+BR+management of your body/mind+don't burnout.

Is there an overall mindset you need to have to make the gains you want?

Obviously not being down and negative about your scores, keeping a resilient face would seem to be something to keep in mind. But has anyone come across something that has helped their scores outside of actually practicing the material?
