While studying for the LPIC exam, I've set up a CMS with a LPIC quiz script on my PC (XAMPP) to help me learn. I passed both exams (101 & 102) about two months ago and I've decided to put the script on a domain to help others pass the exam: https://mrtux.co.uk/test.html. You need an account (you do not need to confirm your email) because the script keeps your passing score on the DB.
My goal is to get the LPIC3 exam next year so I'll add the tests to the site in the near future.
Good luck & happy learning!
