I agree with INNflight, that training is the key.
So I did: I got Skytest and did it again, again and again with that software and the official DLR-CBTs. I repeated all the tests until I got sick of it - several weeks in a row.
90%, it's just getting used to it by repetition again, AGAIN AND AGAIN.
The pass rate for ready entries is, however, higher (something around 50% for the first step, the GU) than mentioned by INNflight.
I seriously advise you: Don't underestimate the test, it's nasty stuff, do that stuff until you're completely sick of it! You WILL be fine. Neglect it, you'll fail.
Training is the key, I can't say it often enough... you definitely don't need to be superhuman, but you need to be well trained...
Good luck!
