I've been studying for Linux+ lately. I have the Sybex book which covers lx0-101 and lx0-102  but I just discovered that these exams will be discontinued at the end of August and replace with lx0-103 and lx0-104. Has anyone taken these yet? I'm wondering what I'm in for. What is covered in these exams that isn't in the older versions? I can imagine that I'll have to dig into Systemd thoroughly but I'm wondering if I'll be able to just top up my knowledge from the 'net or is this a matter of starting all over?
