Congratulations @katiejune! The PE is difficult enough but to balance family life with such young little ones is beyond my comprehension. Hope you get a chance to relax some this weekend.
It was pretty awesome to be part of it and to get an understanding/appreciation of all the work that is put into creating the exam. I highly recommend being part of it later on.
having had participated in the meeting to determine what is passing I can promise you it is not a guaranteed 70%, there is a lot that goes into it.
