Haven’t read Schweser, but I’d do the abridged version of reading 2, and the CFAI text for ROS. The topic tests are asking very detailed questions on ROS, and I think eventually I’m going to have to go over the precise CFAI text like 10 times – may as well start highlighting that now.
The insanely-long Reading 2 describes every possible permutation of how they could asked questions on the code and standards. I remembered most of it from L1. Even the first 40 or so of the EOC’s must have been identical to L1. I just broke out some revision notes from L1 for that, and hit the 60-odd EOC PP.
