Hi Rashmi,
I had the same worry as I was mostly hitting marks within the 70s but ended up writing the exam and passing it. It's up to you to assess whether you feel ready but in my opinion, if you have made enough time to really understand where you've gone wrong in all those practice exams then I would say it's worth a shot at writing it.
Good luck either way!
My exam date is July 9th and today I took prepcast exam 6 and got 69%.
My score have been around 69-75% on the other exams. Please need your advice in order to pass the exam if I should reschedule the exam for end of July or take it on July 9th.
