Should I analyze Practice Test 1 and 2 after taking it

Hi,

Looking if Greg has mentioned anything about this, how should I study practice test 1 and 2 after taking it? Should I deliberately check to see why I got some questions wrong and really analyze it? The reason I asked is that if I do so for both PP1 and PP2, then when I need to take them again in the future, then I already remembered all the answers. It wouldn’t be helpful to gauge my performance anymore. Does Greg has any video talking about this? Or if you guys have any advice?

Thanks,
John
