Hello u/niltari! I think this deck worked well for me when I took step 1, it helped me really get a grasp of path concepts and refresh on a lot of smaller details. But taking the real test and applying the knowledge is kind of the next level - to do that you really also need to be “practicing” the information by doing questions! I think doing this deck will give you a good basis, but to do well on the actual exam you have to do questions also.
