Wow, congratulations on your baby! :) Besides covering everything in the ATI manual, I recommend purchasing additional TEAS practice exams and doing one a day. (I think I bought the McGraw-Hill and Test Prep Books practice exams. These were just okay in content, but I wanted to work on my ability to focus.)
Every percentage point on the TEAS is worth about 2 points for the application! Crazy! If everything transfers okay, I think I have a 46 for my GPA and a 43 for my TEAS.
Good luck on the new teas exam! Although they mentioned the level of difficulty hasn't changed, I'm curious how it compares to the old one. Also, I wonder what the cut-off score for spring will be. If it hikes up another 3 points, that'll make it 81.
