So how did you score? Any of them you scored a 2 or lower on, get proffesional help on. An online course or two, maybe a consultant that can help.
If you scored a 3 on something, just some light brushing up will be ok. Read a book or two and get some advice on it.
Scored a 4 or 5, you're doing great! Just make sure you are up-to-date on this subject.
