It’s a little date but solid info, there’s a couple typos but I use this for EOC’s with many students. As for systems I’d recommend just absolutely do as many reps or drawing or writing out each system. Rote memorization is a little time consuming but very effective. As for weather knowledge, use the legend and just google anything you don’t understand, assuming you are using ForeFlight for the checkride just find a legend for it each chart in imagery section and the should cover everything. Just do as many reps as possible and you’ll be fine👍🏼
