Penguin Tutor is a site focussed on helping you get the most out of Free and Open Source software and hardware. The main focus is on the Linux operating system, getting started with electronics and the Raspberry Pi. The electronics section includes interfacing with the Arduino and interfacing to the Raspberry Pi GPIO pins.
Originally created to provide practice exams for those working towards Linux Professional Institute Certification (LPIC), the site has been expanded to provide tutorials and guides for Linux software and the Raspberry Pi.
For anyone looking at Linux certification there are a range of Linux tutorials to help you with your studies as well as practice exams for the LPIC (Linux Professional Institute Certification) series of exams including the LPI 101, LPI 102, LPI 201 and LPI 202 practice exams. These exams cover all flavours of Linux, including those using RedHat Package Management tools and Debian based management tools and are also suitable for those looking at Novell Certified Linux Adminstrator for SUSE Linux Enterprise.
Most other sites that offer practice exams either ask you to sign up to email adverts, or give a small sample of questions to encourage you to buy their full product. The exams on this site are completely free, do not require you to sign up for any junk mail, and I do not have an alternative pay for version.
There is no charge for any of this, funding received for this site is from the adverts.
There are a number of different penguin images located throughout the site. Keep your eyes open and see if you can spot them all. You can also see these on the PenguinTutor Facebook page.
