i'm retaking in february as well... got a 161 last june, but couldn't retake since because i played college football and that kind of eats up my saturdays...
was extremely frustrated with the 161, missed 20 questions, but 9 of them came in the final section, which i wasn't fully prepared for because of the stupid 4 section practice tests... i thought that 5th section wouldn't effect me so much but i was wrong
