Using RHCE study guides for RHCSA

How much am I going to overlook from the RHCSA objectives if I'm using all the suggested RHCE study materials? Ultimately I will be getting my RHCE, but it appears as if they have mandated that RHCSA become a prerequisite for the RHCE cert.
Is a roughly 2 month time frame reasonable to achieve both certs for someone that has more than just a passing familiarity with the operation of a linux box minus the server admin portions?

I took my RHCT with only 3 months of practice try just to learn the comands and BE SURE to complete some pre exams, I would suggest you buy the Red Hat® Certified Technician & Engineer (RHCT and RHCE) Training Guide and Administrator's Reference and the Hands-on Guide to the Red Hat(R) Exams: RHCSA™ and RHCE(R) Cert Guide and Lab Manual if you can handle to do both of the end of exam without problem then you should do well
Do the follwing thing:
1 Month
Study the RHCT book and after studying each chapter practice it
2 Month
Review withRHCSA™ and RHCE(R) Cert Guide and Lab Manual
3 Month
Practice everything and try to make some pre exam
and after that you should do good I will be taking RHCSA an RHCE again I took last year RHCT and in matter of 3 months I passed the exam without problem.
