Berkeley Study Guide for NBEO Part I (Book 1)- Applied Basic Science. This is the first of two books for the Berkeley Study Guide Part I. Please see the following link for the second book: http://tinyurl.com/83ba9k7. With a more user-friendly format, and additional Boards-relevant material, the 13th edition is a proud new offering by the UC Berkeley School of Optometry. The Berkeley Guide is continually revised, updated, and improved to ensure that you will pass the National Board Exams in Optometry the first time. The comprehensive review of optometric material we have compiled into this Applied Basic Sciences Guide is similar in format to the first part of the National Boards. Within this guide, information is organized according to topics suggested by the NBEO (National Board of Examiners in Optometry) from 2018.
