I've created a new web site with information on the LPI Certification program, including practice exams for the LPIC 101 and LPIC 102 exams.
The website is http://www.penguintutor.com and practice exams are in the certification section of the site.
I created the site because I was dissapointed by both the quality and price (in terms of money or spam) of the other practice exams on the Net. These practice exams are completely free, and include questions based on the latest syllabus from LPI.
Please take a look and let me know what you think.
