Divine Intervention free 120 review

So I have a question about Divine Intervention. I see that there is a PDF online which he follows. From what I see, there are 14 podcasts, each being over half an hour. This would take my entire day to do. At that point, I will be 3 days out from the real deal. Would you suggest I do everything? Or if a question makes sense, to not use it? I am worried. I have other things to review and unsure what to prioritize. Please advise!

Also: would the interactive free120 and the PDF Free120 have the same questions but in different order? Or are they different questions ?
