I have to agree with the >2015 book suggestion. I took the old exam, but because the scores got outdated by the time applications rolled aorund, I had to take the new test. I thought about using my older books, but am so glad I bit the bullet and bought new ones. I got brand new TBR science books and was pleasantly surprised by all of the new passages. It's worth the money and hassle, and let me just warn you now what a pain it is to print the form, fill it out and mail it in. But in the end, it was more than worth the trouble.
