Positive correlation between Grades and Teacher

With my Grade 2 practical exams coming on 30 Aug, and because it is time to register for the 30 Oct 2010 theory papers, I had a discussion with my piano teacher on how we will proceed after I am done with my Grade 2 practical exams. She feels that if I were to move and prepare for Grade 3 exams (both practical and theory) as the next milestone, it would be a waste of time, since the pieces which I am playing now (from the Keys to Stylistic Mastery) is already Grade 3 to 4 level, and that she feels I should be able to cope with Grade 4 requirements (but need to practice lah). So, it would make more sense to move direct to Grade 4. So, starting 1 Sep, I will be officially moving to Grade 4 and starting the following books:-

1. Grade 4 Scales, Arpeggios and Broken Chords (there will be a lot more than what I have now)
2. Grade 4 Theory (after finishing the Grade 3 book, which is finishing and some Grade 3 past year exam papers)
3. Grade 4 Aural (doing it directly, no need to go through Grade 3, she says should be ok)
4. Grade 4 Sight-reading (so scary!!!)
5. Grade 4 exams pieces

and continue with:-
1. A dozen a Day Book 2
2. Keys to Stylistic Mastery 2

Not counting the 3 months which I rested when I gave birth and adjusting to the new member in the family. This is the start of the 24th month into my piano studies, which will also be the last month in Grade 2 whether I pass the practical exams or not.
So, summary of time spent on each grade (for those who are interested):-
Beginner ------ 6 months (no exams)
Grade 1 ------- 8 months (no exams)
Grade 2 ------ 10 months (theory & practical exams, 3 mths of weekly lessons & 7 mths of alternate week lessons)
Grade 3 ------ skip
Grade 4 ------ starting from 1 Sep 2010 (alternate week lessons)

But I am just thinking, most of the times, how fast you move across the Grades depends on your teacher right? If the teacher is someone who is not very demanding in terms of excellent performance and think you are ok ok, would tend to move a student faster through the grades. And for one who is more by the book, step by step approach and a perfectionist would tend to move you slower through the grade? Coz, I am just thinking, skipping Grade 3 is definitely a no-no to my previous teacher. I mean, I don't think I will be allowed to skip Grade 3 totally if I were still with Jennifer. But my current teacher thinks that she is comfortable moving me to Grade 4.

Anyway, I am glad that I will be promoted to Grade 4 next month. What an accomplishment! Yeah! But which means the lesson fees will go up. Aiyo!
