I've considered these, but haven't taken one yet. The sound of it all makes me a bit nervous... but then several people on here say they're decent & OK-to-do jobs.
I too, can figure out most tests (except higher math!) pretty easily. It would be weird to fail on purpose, but I could do that.
The one thing I didn't know ~ or even think about ~ was removal of all jewelry. What?! I have three small sterilng silver 'eternal loop' earrings in each ear that are a gigantic PITA to remove... well, actually, they're more of a gigantic PITA to put in... so I never remove them on purpose. I haven't removed them on purpose since I put them in, in 1997. The only time they were removed was after my horrific car accident in 2001, by hospital staff, to prepare me for an MRI ~ until they found out I have a bunch of metalwork in my back from previous surgery. Then, about a year ago, I accidentally ripped on out when it got caught on a sweater. Despite searching, I was never able to find it... so actually, I now just have two on one side. Heh.
Also, I wear five rings ~ all sterling or stainless, all very simple design. Each is a sentimental piece. I do remove those when I shower, but every now & then, as my weight changes, there are some that just will not come off no matter what I do. Right now is one of those times. I can only remove one, and that is after considerable effort.
So... the removal of jewelry makes this one a no-go for me. What is the purpose of that, anyway?!
