Exit hessi! Help please!

Hello, it's my first time posting here and i'm hoping I can get some help. I took exit hessi version 1 today and didn't make it. I thought I was prepared, I studied really hard. Some of those questions were unbelievable! How does this work,after this version is it the second or whichever one they decide? I have study guides from a friend for version 2, but i'm afraid to focus on these topics and it turns out to be completely different? I don't really know how to prepare, and can't afford to buy study materials. I had to quit my job to make it this far, and now with two weeks left it seems like it's just getting harder. We can "walk on graduation day" but it doesn't really count until we pass this thing. any info would be greatly appreciated. Thanks.
