Hi Rich,
Thank you for your reply.
Answers to your questions :
When you took your CATs:
1) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
I did not take entire tests in the beginning but later on, closer to the test date, I had started taking the entire CAT
2) Did you take them at home?
Yes. All tests.
3) Did you take them at the same time of day as when you took your Official GMAT?
No, not at all times. Few tests were taken at the same time.
4) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)?
In the beginning, when I use to take full length tests at once, I was scoring around 560-580. This made me feel very nervous and I started getting anxious during my verbal sections(I use to have severe anxiety issues, which are somewhat in control now). Therefore, I decided to take sectional tests after preparing for each section separately.
Towards the test day, again, I had started taking full length tests.
5) Did you ever take a CAT more than once? Had you seen any of the questions BEFORE?
No. I did not take the same CAT more than once. However, sometimes, I use to get questions which I had done before during practice.
Do you think I should think about preparing again?
I don't think even a 700 at practice test will put my confidence back.
