Hi! PAK has created a weekly GHDP Practice Question that is free to download. Every week, on Friday, a new question will be posted, and the following Friday, a model solution will be posted. Again, this is a free resource for anyone to use. For students who do purchase a PAK product, there is also the benefit of having the ability to submit your answers for customized feedback from the instructor. All you have to do is go to the PAK website, find the GHDP Exam page, and download the question.
Good luck, and let me know if I can help.
