Here's my take on the new OAT:
The only changes are in RC and QR. Current RC - number of questions vs time gives you 1.2 min/question. The new RC will give you 1.25 min/question with shorter passages so it should be easier

. The QR can go either way, less questions but different materials and the time remains the same

The OAT
.Whats New? Update as of 3-6-06
A few changes are planned for the OAT; however these changes will not be effective until sometime after July 15, 2006. Until that time the current description of the test in the Examinee Guide remains accurate. These changes will not impact anyone who tests before July 15, 2006. Changes will only occur in two sections of the test, most of the test will remain unchanged.
Survey of the Natural Sciences
There will be no change to this section of the test. The information in the Examinee Guide remains accurate and the sample test provided remains the same.
Reading Comprehension
Current Test: The current version of the Reading Comprehension Test consists of three passages and a total of 50 questions. Each passage is associated with approximately 15-17 questions and a total of 60 minutes is allowed for this section of the test.
New Version: The purpose and content of the test will remain the same. The description of the content in the Examinee Guide remains unchanged. The changes that will occur in the test affect the length of the reading passages, number of questions, and time allotted for the test. The
passages will be shorter and there will only be 40 questions on the test. The number of questions associated with each passage will range from 10-15 and the time limit for the test will change to 50 minutes.
A new sample test, reflecting these changes, will be available online several months prior to the change in the test. If you plan to take the test after July 15, 2006, check Important Updates for new information.
