S or N

I've had some trouble recently with finding out my type. On the human metrics personality test, I always come out as an ISFP. However, every other personality test I can find online I come out as INFP.
I don't know WHY this is but I'm putting it down to the fact I don't really understand the questions for the main personality type test. They're worded weirdly and it hurts my brain, these other tests are far simpler and easier to understand! The answers I put are 100% honest (to the best of my ability?) but I'm just wondering if

1) Someone could dumb the test down for me
2) If these other tests are as reliable as the Human Metrics one
3) If there's any questionnaires or something I can do on here that are easy to understand and you guys could input?

Im new here by the way so HI!

thank you for any help posted x

What activities make you feel the most energized? What do you talk about, if you can talk about anything you want? How do you relate to the Se-Ni axis vs the Ne-Si axis?
