Open Question: What could my violin teacher be thinking?

I've been with her for about 8 months and have been playing a year she's been playing since she was a kid,is in the topeka symphony shes been teaching for some time now and i can tell she has a lot of students too I first started out with volume 1 of muler rusch book http://www.sheetmusicplus.com/store/smp_inside.html?item=273436&cart=3441700157256531&type=image&page=01&cm_re=detail-_-lookInside-_-thumbnail: When i got done with it i began sight reading and took tape of violin and started on this book http://www.sheetmusicplus.com/store/smp_inside.html?item=1429844&cart=3441700157256531&type=image&page=01&cm_re=detail-_-lookInside-_-thumbnail:inside in it we're now doing spiccatto staccato marcatto dotted quarter notes and so on heres a example of what i'm doing now building technique book http://s129.photobucket.com/albums/p224/spend782/?action=view¤t=100_2968.jpg along with that she gave me a binder that has two other books we go in and out of one that has third position and the other that has odd rhythmic patterns it's the most challenging but also my favorite heres a picture of a piece i just got done with http://s129.photobucket.com/albums/p224/spend782/?action=view¤t=100_2961.jpg my teacher said it was hard but i did a a good job on it but now she said we're going to take a break on that book and focus on this one http://www.sheetmusicplus.com/store/smp_inside.html?item=386788&cart=3441700157256531&page=cover&cm_re=detail-_-lookInside-_-cover+text+link she says ppl who have been playing 2-4 years are in this book and i know it's the 2nd volume of the three but i find that hard to believe since it looks simple it looks like what i'm already doing in the building technique with beautiful music book so i'm a little confused as to what she's thinking and then after the pink book we're going to start suzuki book 1 idk what do you think?
