I studied very hard and still failed the exam. I got a 642, not sure what that means.
1) what is a 642? I.e. how much more studying do I need?
2) what is the best book and what is the best practice tests?
I have no experience so some of these concepts were very hard. Should I have taken network + first. Thank you.
