Passed RHCSA , going for RHCE

Hello guys , I Passed RHCSA after 5 days preparation of mike jang's book and doing practice labs on CentOS Host and CentOS VMs , there wasn't much new info as I got linux+ fresh 1 month ago which in my opinion was mandatory before taking in RHCSA , I will chill for few days then setin again for RHCE , does jang's book remains a good material for this one ? or do I need to switch?

So far, I'm using Linux Academy, certdepot and Mike Jang's book. I'll get Sander Van Vugt's book a bit later.
