Honestly, the more times you fail, the safer driver that you will be in the future. I read a report the other day that said that people that pass on their first or second time are most likely to get into a crash or accident in the future. I've failed a few times too due to nervousness, not because I'm a bad driver and I'm sure it's the same with you if you've taken 7 tests. All this is experience, it's good you learn these things now without your license rather than getting lucky the first time and driving like a complete idiot and putting everyone in danger.
