How to sign up or begin taking the courses in aleks

[Ideas]

Force a new assessment in the Master account, Is it accessed from 'New' under 'Quizzes' in Master account? And if i score up to 70percent, have i passed?

If you score 70% or higher on the assessment, yes.

Yes, in the master account. I don't remember the exact location, but it's at the bottom of the page, sort of small. I think it's a checkbox.
