Retaking the teas V ; my last chance

I took the teas v last month and now I'm taking it again, my second/last attempt. Only 2 attempts for every 1 yr period.My weakness were math and reading comprehension. Ive been practicing reading comprehension from any test practice books I can find. I even used the study guides for SAT and ACT just to find reading questions lol. I still haven't started on math which needs major work too since my score on numbers and operations was 50% on the 1st time. My arithmetic really sucks so bad.And now I have about a week to get ready to take the teas again. By the way, about the unscored questions, how do they determine which question is unscored in the test? Do they pick the wrong answered ones or ...?I am scared and anxious and nervous. Passing this test is my only hope. -sigh-
