Thank you RajNo, you are short of 0.5 in reading. It is the individual scores that matter. You have to get at least 6 in each of the sections - Listening, Reading, Writing and Speaking to be eligible for Express Entry.
Be warned that 6666 LRWS is only the bare minimum requirement - you will NOT get a decent CRS score with the minimum IELTS score. To maximize your CRS score, you need a CLB-9 (8777 LRWS).
