IRS provides On-Line Training Classes within Link and Learn.  They cover the same modules as the presentations above.  However, they are more generic and may not be the same scope as we do in TX3 D5 - but very close.

You can also  access this by going to Link and Learn,  selecting "Link & Learn Taxes Lessons" under Quick Links then selecting "Click here to see the content of each course" in the left column.

Please note that you must be logged OUT of Link and Learn to access these menus.  Once you log in, you will be taken to the certification tests and you must log back out.
