考 鋼琴六級定七級好？

From my own experience, Grade 7 is better if you want to continue on Grade 8. Grade 7 syllabus can prepare you more for Grade 8 exam, especially in the aural part. However, I would suggest you to practice a bit longer before taking the Grade 7 exam since you have put down piano for a few years and just pick it up recently. Grade 7 is not hard to pass, but it's hard to achieve a high mark. I have practiced for around 1.5 years before I take the exam, and I got a pretty decent mark. Moreover, I would suggest you to have more practice in sight reading. I have once put down piano for around 1 year because of heavy school work, and it took me a lot of practice before I finally have my normal sight reading skills back.

你可以試下考7級，因為5級同6級有少少不同，考7級有高難度!!
希望幫到你!!!!!!!!!!!!!!!!!!!

我建議你考七級啦，因為你都考完5級，而且又學左一排，六級同五級差唔多，考七級就會更接近八級既難度，Aural果part都要求高D，我係3->7->8咁考

雖然我是2,4,6,8上（of course考咗樂理）
但我覺得考六級會好過上七級咯。。。（個人意見）
不過都系看看你自己有冇把握，你自己覺得ok咪上咯。講真，如果你明年考的話，七級是ok ge~
