I've been playing tennis my whole and am roughly a 5.0. I've taught tennis before, but not for any length of time. I have a good knowledge of the game but I wouldn't put myself in the same league as many people on this sight. I'm wondering if anyone can comment on how hard the various elements of the test are -- and if a decent player can be assured of getting at least level 3. Any general info/strategies/advice on this would be appreciated.
