class a driver

Hey fellow brown members. My building is new and I just wanted to get some tips for feeders. I live in California and have the CDL handbook I'm just not sure on what sections I should read and what sections I shouldn't and if I should focus on one more than the other. Thanks boys.

Im currently going to intergrad to be a package car driver. But i heard that they will need a good amount of feeder drivers due to amazon in the area? is that true, also i was wondering if i didnt pass intergrad for example would i be able to come from the streets as a temporary seasonal driver...
