I collected a list of machines/labs/challenges from various sources here which I think can help to prepare for the exams below. Finding perfect fits is of course difficult, but I tried to filter out machines that are clearly out of scope, don’t fit difficulty wise or are too obscure. The list also just includes machines I have personally solved & has no particular order.
If you have suggestions please let me know! I’ll try to update the list every now and then.
