I take my exam tomorrow and just learned from this video that they came out with a 1.2 version of the reference manual. Does anyone know the differences between the two versions?
If you're curious about the changes from the 1.1 to 1.2 PE Handbook this is what we are seeing so far. Let us know if you notice any changes too! Added new section 5.1.6 "Design Traffic" (1 page) 2.
