ECA - Bachelors or MS?

Express Entry ECA
4

A follow up question. I’m creating my WES profile

  1. I’m planning to mail both Bachelors and MS transcripts, yo be on the safer side. Should I then ‘Add credential’ for Bachelors on my WES Canada profile?
  2. Referring to this post Education Credentials Assessment (ECA) for all degrees?
    I’m assuming I can’t get points for both Bachelors and MS because their hierarchical. Is this correct? In that case, would I cause confusion in my WES profile if I added my Bachelors as a ‘credential’? Would it mean I’m trying to claim points for both Bachelors and MS?
  3. In ref. to the same post above, are there situations where Bachelors points can be added to MS? How would that look on EE profile?
  4. Are there any recognized certifications (like Six Sigma, SCJP etc) that can increase CRS after creating EE profile?

Thanks,
VJ
