Not sure if this helps, but I find unless I lower my security, and go into Security - Privacy - Sites, and add the URL, my scores don't "take", for lack of a better word.
Only 1 company was a pill, and wouldn't let me re-take the test for 6 months or something stupid, so on principal, I haven't re-visited the company (Sinclair)
Not to change the subject, but are they all that? Am I missing out ?
Good luck on your test --OP
