There are many proven factors that will affect the way your brain reacts when testing
. Your immediate environment such as what clothes you're wearing. What you ate the following night. Your comfort level such as being hot or cold. All of these things can affect your scores. I can't stress enough to read up on as many books and studies as you can along with taking your practice tests (while focusing on techniques). You will be surprised by the information you find that can help you. There's a lot of info out there. A lot of it is just re-hashed so you may have to do a lot of digging, but I promise you in the end it's worth it. Some of the information in this article were things my daughter ran across when signing up for her practice tests and ordering books that I found to be interesting. Most were taken from the book listed below which also has a lot of other tips I recommend, but don't have room for in just a single article. I HIGHLY recommend http://www.shrinkmylink.com/xhvhton . I hope this helps everyone and remember to keep an eye out on future articles coming soon!
