testing linkedin skill assessment test

I try some of Linkedin skill assessment tests.

from three tests outlook, excel, and wordpress: I got badges from outlook and wordpress, after retake tests for excel, still not got badge.

why I failed in excel?

  1. I think I did incorrect answers for 1-2 from all 15.
  2. from 1. numbers of persons whom got excel test may much more than wordpress and outlook for sure, 1 from 15 can make you fail from upper 30% bound for sure.
  3. it was good exam not too hard or too easy, 1:30 minute make good period for the tests
  4. many of excel test took one whole minute to understand the question. 30 seconds is a good grieves for the answering.
  5. will try for agile and project manager test after this.
