Failed first HESI practice test, please help

I failed my first HESI A2 practice exam (at http://www.hesiprep.com) and am freaking out a little as my test is the day after tomorrow. Part of the reason I'm stressing is because I'm still not sure what exactly is going to be on the test! I'm applying to a BSN program at LSU and their website doesn't specify which version of the test I will take. I've gathered that the test I will take is the HESI A2 V-1 with CT, since that's what pops up when I input their dept ID in the HESI registration.

Does anyone know exactly which sections this version will cover?

Or what the A2 and V-1 mean? I figure CT is critical thinking.

Also, I'm concerned that the practice test I took had many questions which my Elsevier HESI study guide does not show how to solve. Like really heavy chemistry and certain math probability questions.

Does anyone have any advice?

Sorry for this rambling frantic post. Just kinda stressing.

Thanks guys.
