Woah!!! I have just read this entire thread through and am in shock! I just wanted to say a few things...
1. GoneChopin, you sound like you don't believe in yourself. If you SERIOUSLY thought that you could make it and jump from G5 - G8, then why are you being so defensive? If you think you can do it, then why concern yourself with these people's thoughts?
i do believe in myself, i do strongly believe that if you believe you can do something and REALLY try with it, you can do it *shrug*
2. I'll tell you why...the people who are critising you are people who are far better than you and than me. Some of them are teachers who most certainly know what they are talking about and some of them have actually done the course that you are thinking about! They are trying to help you! They know what they are talking about and they are far better than you or me. If you could stop yelling at them and LISTEN to what they are trying to tell you, you might be able to benifit.
i already have

ive already said im doing Grade 6
3. I took my G5 over a year ago, and I still haven't started the G6 sylabus yet! I'm taking my time, like these people are suggesting. I am broadening my skills and trying to iron out problems like fingering and other gritty stuff. I am sort of in a rush as well. If I want to go to music college, then I need to get G8 and a diploma as well, but there is absolutely NO point in being able to play a G8 piece and not be of that standard. for instance, I am sure that most people on this board could find a G8 piece, spend ages and ages learning it (note, learning...not practising) and then be able to play it and wow people. But that doesn't mean they are of G8 standard and then when they want to go to music college and they are in their audition playing their memorised G8 piece, the music specialist will be able to tell you aren't really G8 and will put a big cross by your name. Also, I can play stuff that is harder. I learnt a G6/7 piece the other day in a week (1/2 hour practise a night) but that doesn't mean I am G6/7 standard.
yeah, i've learnt diploma music and i KNOW im not that standard
4. I know you think that everyone is trying to get on your back and that they are all out to get you, but you must understand that you did sort of start it off by saying in your first post that you were going to jump from G5-8 which is a pretty HUGE jump and these people were only trying to help out and give their advice to you, because 111 at G5 isn't that brilliant and you said yourself that you were shocked at passing! Now, someone who is shocked at passing G5, SHOULDN'T be considering jumping straight to G8! It's just not right!
yes because i swore i failed my G5, and i've already taken the advice of doing G6, as for getting on my back,

maybe it is whats happening?
Sorry for going on!!
