Not having read much info about theese exams, as I am planning to do them next year after I get a PPL, are they all multi-choice exams as per the PPL's. or are they written??
IMHO you should always aim for 100%, not for anything like one-upmanship, or god complex etc etc, but the simple fact that knowing and UNDERSTANDING all aspects about a subject must be far better than scraping a 75% pass, with a few lucky guesses etc?? Like eveerything else in life, there is always somthing new left to learn about anything......... and thinking you know it all is the fastest way to a fall.
