Thanks for the help! So quick with the response too! Okay, I found a list of required coursework and I am missing a few things to get a waiver in geosciences. I think I will take all three subtests (118,199,122) at the first session and see how I do. I think I am a strong test taker and this gives me a back up test date anyway. Now, Im starting to study and get a few resources. I have read through most of your prior suggestions and it looks like you guys reccomend these: Conceptual Physical Science, 2nd Edition, Hewitt CA Geology, Harden Are there any other resources you recommend for the 2 general science subtests and the Geoscience subtest? For example, what is the best Earth Science book to use? Are the books recommended by the CSET Annotated Resource list useful? One dates from 1985.... Also, I can add another Subtest at anytime right? Like if I want to do Biology later, when I have more time, like after or during my credential program?
