Since you have a teacher, why don't you rely on your teacher to identify the repertoire you need to learn... and when you need to start it? Often, learning repertoire way above your current level is not productive and leads to poor results: you 'learn' the repertoire after many struggles, play it poorly, and ingrain bad habits that require 'unlearning' when you are truly ready for it.
I have a teacher; so when there is repertoire that I want to learn, I haul it to lessons. I either get the go-ahead or the 'not yet'. That is only one of many reasons I have a teacher.
You are fortunate to have a teacher direct you. My advice, rely on your teacher to direct you in developing the skills and repertoire you need.
