I used the REA prep-books for the MTEL Communication/Literacy and the MTEL Middle School Mathematics and overall these were pretty good, however, this MTEL General Curriculum prep-book by REA is aweful!The History and Child Psychology sections do okay at giving over a short summary of the content of these sub-areas, but the Language Arts, Math and Science sections mostly just explains what is on the MTEL so you know what to study, rather than giving over the "cliffnotes" of this information. So this book is pretty useless for these later topics.Some of my friends have recommended "What Every 5th Grader Needs to Know," and "What Every 6th Grader Needs to Know." Why both I'm not sure; I haven't looked at them yet.
