I was reading my "How to prepare for the GED" book, and it said there was a course in this program where some one will give me feedback on my practice essay. Please let me know where this is! Thanks. 
Hi! When you take the writing essay practice test after the initial assessment, the essay will be graded by a teacher, and we'll send you feedback. That's what the book is talking about. You can go directly to a practice test if you feel you need the feedback. If you have trouble finding the link to take a practice test or have any questions about it, just call 800-460-8150 for help.

You can also contact Elizabeth at her blog for help and feedback on writing your essay:
