Good Afternoon Gents, 
  
I am set to take the AFOQT for the first time this Tuesday at a local AFROTC Det and was just informed that this will be the last time the AFOQT Series S will be administered. After this test date, all future tests will be the Series T. 
  
Does anyone know what the difference will be between the Series S and Series T? Is it a whole new test with a different format and subtest structure? WIll there be substantial differences between the two? 
  
I am seeking guidance on this because in the event of a retest, I wouldn't want to take a test that is a completely different from the first test that I had taken.  
  
Thanks in advance for all the help with this guys.
