I would lump this with my first answer, which is to leave it up to the teacher. Don't ask (in my opinion), the teacher will promote you higher if s/he thinks it is warranted.
Rank really can be arbitrary, and it is good not to get too caught up in where you are, in particular compared with others. We all know instances of folks who are way past the level where they should be for their rank, and visa versa. Just practice for yourself, and unless you need a certain rank for a certain reason (such as to be able to join advanced classes), then there really is no need to get worried about it.
Passing a test is only part of the equation.
all the best,
