Yes, I spent my Saturday morning locked inside Nashua High North for four hours taking the incredibley boring SATs. For the past month I have been cramming my brain full of information and now I await my fate...I mean score. I plan on avoiding a second round at all costs. A little advice for those who are still looking forward to their turn: Bring a book or something to do because if you finish early staring at the clock and watching the seconds tick by is not entertaining. Don't leave your cell phone on, they tend to frown on that. And don't forget to sharpen your pencils...not good. Last but not least, don't get nervous! I didn't so I can honestly tell you there isn't anything to be nervous about. Good luck!
