I have all the Manhattan study guides, but I can't for the life of me find a good explanation on what OG Archer is or where I can find a link?
I have heard it's a great supplementation and requires the Official Guide (OG), which I have. I am looking for the most useful and challenging prep resources possible, and I have been reading that this is a good one. If only I could figure out what it is, how to use it, and where to find it. Google searching does not help. The only people who talk about OG Archer already know that the heck it is haha.
