I can only hear the part 1 and part 6, and I haven't taken the Ibt myself , so I can't score your answer.
According to what I have heard, I find you orgized your ideas clearly and coherently with transitional words and key words. In addition, you elaborated the supporting points. Thus, I think you really can do a good job here in the speaking section except for some minor errors such as get energitic shou be energy.
I apologise for lacking the ability of giving more comments.
