Question regarding CCSE R74 Courseware

Hi all,

I have achieved my CCSA R71 about 6 months ago and now would like to proceed to the CCSE R75.

I am trying to decide whether to study from the CCSE R71 Kit or directly from the CCSE R75 Kit. It just seems like the CCSE R75 lacks lots of the subjects on the R71 book, such as dynamic routing, QoS, DLP etc.

Can anybody advise?

Thanks!
