i've done the solo times and it only comes to 7.3 hrs?!
Then you were not qualified to take the Skill Test! JAR-FCL 1.030 clearly states that you may not take the Skill Test unless you have completed all of the flight training (25 hours dual + 10 hours solo) and all of the theoretical exams.
Who signed the certificate of trainig on your application form? Why did the examiner not check it? Technically your skill test is null and void!
