I just purchased two books:
Smith's
CompTIA Linux+ Study Guide: Exams LX0-101 and LX0-102
and
Tracy's
LPIC-1/CompTIA Linux+ Certification Exam Guide (Exams LPIC-1/LX0-101 & LX0-102) (All-in-One)
I have a tiny bit of quasi-related experience (took a UNIX course as part of a continuing education program at a local CC about a year ago).
I've heard that Tracy's book is more beginner friendly, so I plan on going through it first, and then on to Smith's. Not sure how realistic it is, but my goal is to pass 101 and 102 by the end of 2014. Does this seem a reasonable goal? I went through A+, N+, and S+ fairly quickly, but I realize these Linux exams are a different beast.
