Charles M. Kozierok has edited and adapted the following comprehensive Guide to A+ Core Hardware. This free training guide was written for the CompTIA A+ Core Hardware Technology Certification Exam 220-231. Each chapter provides a great set of practice questions and answers with explanations.
In September 2006, the CompTIA A+ (A Plus) test was updated, and now the candidate takes the CompTIA A+ Essentials test along with one of the four other tests (220-602, 220-603, 220-604, 220-605). However, at this time A+ candidates are offered a choice between the 2003 and 2006 versions of the exam, and in 2007 it is likely the 2003 A+ track will be discontinued.
