This might sound like a stupid question but I'm assuming the CompTIA Essentials and Core Hardware are one in the same thing? Please correct me if I'm wrong!

I have to admit I didn't even know CompTIA existed until I moved (from Ireland) to the US a few years ago when I noticed this thing called A+ as a requirement for most IT jobs...
I'm about to certify (A+) over here in the US and I'm ready for the Core Hardware Exam (OS will come with the next pay cheque/Check!

)... ready to schedule my test but I wanna make sure I sit the correct exam and don't flush $163 down the (bog as we say) toilet!
I have to admit I'm more excited than nervous about this exam, I'm 100% ready for those really annoying questions. Any and all advice on what to look out for on the exam would be great!
Thanks in advance for your responses!

Wish me Luck! :P
