Hi Daniel,
I have completed my exam yesterday (19th Oct)!! And I got T/AT/AT/BT/AT -- Over all AT
My Scores during Mock Tests(PM PrepCast) are as follows -
1st Mock (65%) - One Week Break + Study + 50 question daily with 10x5 Q sets ( Scored 60%-70%)
2nd Mock (70%) - One Week Break + Study + 50 question daily with 20-20-10 Q sets ( Scored 70%-80%)
3rd Mock (82%) - One Week Break + Study + 50 question daily with 20-20-10 Q sets ( Scored 80%-90% occasionally 100%)
And Final PMP exam - T/AT/AT/BT/AT - over all AT
So if You are scoring around 70-75 consistently, it means you are almost ready just need the confidence that's it.
Try to do 20-20 Questions sets with timer and then analyse all correct and incorrect answers, this will clear yours knowledge gaps and keep your pace intact.
Just think this way- that you just need to do 8-10 more questions correct in order to achieve 80% since you already scoring mid 70s.
After completing the mock test always try to make sure that you go back and review only correct 8-10 question and make sure they are correct. if you go try review all the question it may happen that you make correct question incorrect in haste.
So just focus only on those questions which you think you can make finally correct by providing them little extra time. Don't try to correct any answer which you have no idea about it may happen you make it incorrect by over analyzing it in review session during last minutes. Since our first instinct are generally correct so trust your gut feeling.
Try this...and I am sure you'll be able to touch so called 80s line... BTW You are ready anyway just cover the knowledge gaps with confidence.
Hope this will help
Regards
