IT Educational Goldmine

Thanks to /u/VA_Network_Nerd whose amazing Reddit comment this page is effectively a copy and paste of.

If you're looking to get into IT,

See if your school provides access to Microsoft DreamSpark.

Play with Windows Server, especially Active Directory.

Register for the Red Hat Developer Network.

Download RHEL and start learning Linux.

Linux is the single most powerful IT skill you can develop to prepare you for the widest array of possible career options.

Don't spend time on an A+ certification unless you really want to be a PC Support Tech after college.
