I haven’t read the original post but these things are not as simple as you made it out to be.  I have posted a lot in this.  You need to fill out the Q worksheets and link it to the T worksheets.  As TaxGuyBill said, there are qualifying expenses for Q that don’t work for T.  If parents are claiming T credits and there aren’t enough remaining expenses for Q, the recipient of the Q, which could be the parents, grandparents,student, etc. will have taxable income and possibly a penalty.
