I did the test this year and passed it without tutoring, therefore I would say tutoring is not necessary. I did, however, practice with free online personality and EQ tests (as medchic mentioned as well)
I would also love it if you could shoot me a message to share some of your tipsHi! I've sent you a message, would be happy to share some tips. Also there are a few free emotional intelligence/personality tests you can find online if you just search up free personality test/emotional intelligence test you should find some.
