A lot of great advises here. And + karma for nerdykarim for reaching out.
I am not a lawyer, nor have I studied it, or been in your situation, so this is pretty general stuff.
In my experience, doing well on tests is all about living the field. Talk about law with your friends, think about law, dream about law. That´s how to pass, in addition to the advise the other guys have given, of course.
Whether to take the bar, or not, is a different story....
