Probably the best path for you is to contact Cori. Advise them of the answers to your test attempts, and ask them for assistance.

I could not pass one of their tests recently and emailed them stating that I couldn't for the life of me figure out the right answer for two of the questions. It definitely paid to email them. Can't help but wonder if it's the same test that I had such a hard time with.
