Tested at 175 what and don't say I.Q because that's not true!
Maybe your test administrators guestimated at 175.
Maybe you actually have a 175 I.Q., but you didn't test at that level because the test flatlines at 160.
Test givers do have a habit of trying to estimate when someone exceeds test limits in each category, but they can't measure accurately above 160.
If this was the case, I could say that I tested at "above 210" because that's what the administers of my last testing wrote, but after reading the entire report, it was obvious the testing was speculation above 160 which they admitted in the report. They didn't think I'd get to read their report, but that's a different story.
Truth is, the test range is done at 160.
