So I am in 7th grade and I have been using the Ace school of tomorrow

Pace books I find them rather simple in the 7th grade books but I am worried that in I go back into the public school system I will be behind in what I am currently doing and I will be held back for not knowing what I am doing I am getting really I mean REALLY nervous about this problem I don't really know what to do I have been working in those pace books for years now and I am kinda regreting doing them I am very afarid I am getting behind in everything and from what I have herd students that have worked in the paces and then went back to the public school system were a year behind!!! I don't want that to happen to me at all I'm just very confused about what to do about this.. Any suggestions?

Thank you,

Sara.
