Hi Reza,
First, and most importantly, the decrease you've noted on your Logical Reasoning sections is probably a combination of a small sample size and (very understandable) nerves. Of the three section types, Logical Reasoning has changed the least from 1993 to today. There have been a few minor changes - "double trouble" questions, for instance, where one stimulus is used for two questions, are less common than they used to be - but overall, these sections have been very consistent.
The bigger changes have actually been in Analytical Reasoning and in Reading Comprehension. In logic games, sequencing games with conditional rules have become more common (such as A > B, or A > C, but not both). In Reading Comprehension, Comparative Reading was introduced, where there are two shorter passages instead of one longer one, and these generally appear once per test. But if you're finding that your performance on these sections has been consistent, then you've adapted to these changes well.
Remember, the test was designed to compare people across years with perfect consistency, so the overall difficulty has not increased, and the format of the questions has been consistent enough that your previous work is still totally applicable.
If there's one adjustment to your study method I would suggest, it would be to keep reviewing the fundamentals in the Bibles - how to distinguish the different Help stems from each other, the Elemental Attack for Parallel Reasoning questions, and so on. Doing nothing but taking and reviewing practice tests, without referring back to these fundamentals, can sometimes make you lose the forest for the trees. And if you're looking for assistance from instructors, we're always
here to help!
Best,
