I agree with you DentalLH, that is the same response I have received from the testing administration
Below is the email I received from the ADA.
"There will be changes made to the DAT Bio and QRT sections in 2015 but there is not a set date. Updates will be posted at
www.ada.org/dat periodically.
The systematic approach for Biology is aligned with academic current curriculum.
The QRT section revisions do not necessitate a change in preparation, as the section covers the same content, just with a little more emphasis.
"There should be no change in study habits or material to prepare."
Have a great day!
