Hi everybody!
Just wanted to add my two cents, as I had been postponing taking it myself at first because I was afraid and will not pass it.
As you know, currently there is no official practice test, but the good news is that there is a workaround hidden in plain sight! The exam allows 2 retakes and you can use the first after 24 hours. I suggest trying it anyway as you get a transcription of the percentage correct in each topic at the end, so if you don't pass you know which areas you need to improve. And you may even get the awesome surprise of passing it on the first try, you win either way 😉
Hope these words encourage you to take the leap, you got this 💪
