Certifications and E-learning modules

Hi, 

I would like to know if the modules covered in the certifications are the same as the E-learning which is available. I've been enjoying the Certified Specialist Payment and Re-imbursement and would like to delve deeper into some topics. 

On the certification there is a contracting module and HFMA also offer a contracting E-learning module. Are these the same as I don't want to be paying twice for the same information? Or are all the certifications and E-learnings separate material? 

Thanks,

Sam
