I'm pretty sure everyone feels the same way
I didn't study prior to the TEAS because I was told I didn't have to take it the first meeting (I ended up taking it anyway)- my adviser said they like to know where you're at before you have time to cram, so I'm not sure how they factor in the significance of your TEAS scores.
Someone who passes every section can not re take the test, however, a person who fails a section can study and retake those sections. I would assume they place some significance on scores where the student didn't need to retake? (at least I'm REALLY hoping for this- I know a few people who retested after the pre-req's and killed it). I have my fingers crossed, regardless
I want into this program more than anything.
My advice is not to stress and maybe invest in both study guides? Good luck!
