Assesesment CDR, 6 bands each, Civil Engineer

Hi. I am a civil engineer and new to this forum. Done my bachelors in 2013. I want to know about Engineer Australia CDR system. If my assessment is not positive or they ask me to apply as civil engineer technician etc. as I have heard BS Civil engineers talking about this, what are my chances for Australian immigration? Will my points be 15 still for education? It is not necessary that I go there as civil engineer, but I want to have Australian immigration any way. I have 6+ bands but less than 7 bands in each module of the IELTS. Can anyone guide me how it will work for me?

Age: 26
Qualification: BS Civil Engineering (not assessed yet)
IELTS: 6 bands each (6.5, 7.5, 7.0, 6.0)
