I had my actual Gmail on Webassessor.com. I am doing Trailhead using Myname@companyname.com(not Actual email just a login name). But I verified Myname@companyname.com account using actual Gmail id(Which  I use on Webassessor).  So, I have question

1. Whatever I will complete on  Myname@companyname.com trailhead then It must show on my webassessor account then What I have to do.
2. Before using Myname@companyname account, I had done many badges using an old Email address which is not exist so can I merge that account on here.
